We cannot talk about web development without talking about Responsive Design. It’s just a given these days and has been for many years. Media queries are a part of Responsive Design and they aren’t going anywhere. Since the introduction of media queries (literally decades ago), CSS has evolved to the points that there are a lot of tricks that can help us drastically reduce the usage of media queries we use. In some cases, I will show you how to replace multiple media queries with only one CSS declaration. These approaches can result in less code, be easier to maintain, and be more tied to the content at hand.
Let’s first take a look at some widely used methods to build responsive layouts without media queries. No surprises here — these methods are related to flexbox and grid.
flex
and flex-wrap
Using In the above demo, flex: 400px
sets a base width for each element in the grid that is equal to 400px
. Each element wraps to a new line if there isn’t enough room on the currently line to hold it. Meanwhile, the elements on each line grow/stretch to fill any remaining space in the container that’s leftover if the line cannot fit another 400px
element, and they shrink back down as far as 400px
if another 400px
element can indeed squeeze in there.
Let’s also remember that flex: 400px
is a shorthand equivalent to flex: 1 1 400px
(flex-grow: 1
, flex-shrink: 1
, flex-basis: 400px
).
What we have so far:
- ✔️ Only two lines of code
- ❌ Consistent element widths in the footer
- ❌ Control the number of items per row
- ❌ Control when the items wrap
auto-fit
and minmax
Using Similar to the previous method, we are setting a base width—thanks to repeat(auto-fit, minmax(400px, 1fr))
—and our items wrap if there’s enough space for them. This time, though we’re reaching for CSS Grid. That means the elements on each line also grow to fill any remaining space, but unlike the flexbox configuration, the last row maintains the same width as the rest of the elements.
So, we improved one of requirements and solved another, but also introduced a new issue since our items cannot shrink below 400px
which may lead to some overflow.
- ✔️ Only one line of code
- ✔️ Consistent element widths in the footer
- ❌ Control the number of items per row
- ❌ Items grow, but do not shrink
- ❌ Control when the items wrap
Both of the techniques we just looked at are good, but we also now see they come with a few drawbacks. But we can overcome those with some CSS trickery.
Control the number of items per row
Let’s take our first example and change flex: 400px
to flex: max(400px, (100% - 20px)/3)
.
Resize the screen and notice that each row never has more than three items, even on a super wide screen. We have limited each line to a maximum of three elements, meaning each line only contains between one and three items at any given time.
Let’s dissect the code:
- When the screen width increases, the width of our container also increases, meaning that
100%/3
gets bigger than400px
at some point. - Since we are using the
max()
function as the width and are dividing100%
by3
in it, the largest any single element can be is just one-third of the overall container width. So, we get a maximum of three elements per row. - When the screen width is small,
400px
takes the lead and we get our initial behavior.
You might also be asking: What the heck is that 20px
value in the formula?
It’s twice the grid template’s gap
value, which is 10px
times two. When we have three items on a row, there are two gaps between elements (one on each on the left and right sides of the middle element), so for N
items we should use max(400px, (100% - (N - 1) * gap)/N)
. Yes, we need to account for the gap
when defining the width, but don’t worry, we can still optimize the formula to remove it!
We can use max(400px, 100%/(N + 1) + 0.1%)
. The logic is: we tell the browser that each item has a width equal to 100%/(N + 1)
so N + 1
items per row, but we add a tiny percentage ( 0.1%
)—thus one of the items wraps and we end with only N
items per row. Clever, right? No more worrying about the gap!
Now we can control the maximum number of items per row which give us a partial control over the number of items per row.
The same can also be applied to the CSS Grid method as well:
Note that here I have introduced custom properties to control the different values.
We’re getting closer!
- ✔️ Only one line of code
- ✔️ Consistent element widths in the footer
- ⚠️ Partial control of the number of items per row
- ❌ Items grow, but do not shrink
- ❌ Control when the items wrap
Items grow, but do not shrink
We noted earlier that using the grid method could lead to overflow if the base width is bigger than the container width. To overcome this we change:
max(400px, 100%/(N + 1) + 0.1%)
…to:
clamp(100%/(N + 1) + 0.1%, 400px, 100%)
Breaking this down:
- When the screen width is big,
400px
is clamped to100%/(N + 1) + 0.1%
, maintaining our control of the maximum number of items per row. - When the screen width is small,
400px
is clamped to100%
so our items never exceed the container width.
We’re getting even closer!
- ✔️ Only one line of code
- ✔️ Consistent element widths in the footer
- ⚠️ Partial control of the number of items per row
- ✔️ Items grow and shrink
- ❌ Control when the items wrap
Control when the items wrap
So far, we’ve had no control over when elements wrap from one line to another. We don’t really know when it happens because it depends a number of things, like the base width, the gap, the container width, etc. To control this, we are going to change our last clamp()
formula, from this:
clamp(100%/(N + 1) + 0.1%, 400px, 100%)
…to:
clamp(100%/(N + 1) + 0.1%, (400px - 100vw)*1000, 100%)
I can hear you screaming about that crazy-looking math, but bear with me. It’s easier than you might think. Here’s what’s happening:
- When the screen width (
100vw
) is greater than400px
,(400px - 100vw)
results in a negative value, and it gets clamped down to100%/(N + 1) + 0.1%
, which is a positive value. This gives us N items per row. - When the screen width (
100vw
) is less than400px
,(400px - 100vw)
is a positive value and multiplied by a big value that’s clamped to the100%
. This results in one full-width element per row.
Hey, we made our first media query without a real media query! We are updating the number of items per row from N to 1 thanks to our clamp()
formula. It should be noted that 400px
behave as a breakpoint in this case.
What about: from N items per row to M items per row?
We can totally do that by updating our container’s clamped width:
clamp(100%/(N + 1) + 0.1%, (400px - 100vw)*1000, 100%/(M + 1) + 0.1%)
I think you probably get the trick by now. When the screen width is bigger than 400px
we fall into the first rule (N
items per row). When the screen width is smaller than 400px
, we fall into the second rule (M
items per row).
There we go! We can now control the number of items per row and when that number should change—using only CSS custom properties and one CSS declaration.
- ✔️ Only one line of code
- ✔️ Consistent element widths in the footer
- ✔️ Full control of the number of items per row
- ✔️ Items grow and shrink
- ✔️ Control when the items wrap
More examples!
Controlling the number of items between two values is good, but doing it for multiple values is even better! Let’s try going from N
items per row to M
items per row, down to one item pre row.
Our formula becomes:
clamp(clamp(100%/(N + 1) + 0.1%, (W1 - 100vw)*1000,100%/(M + 1) + 0.1%), (W2 - 100vw)*1000, 100%)
A clamp()
within a clamp()
? Yes, it starts to get a big lengthy and confusing but still easy to understand. Notice the W1
and W2
variables in there. Since we are changing the number of items per rows between three values, we need two “breakpoints” (from N
to M
, and from M
to 1
).
Here’s what’s happening:
- When the screen width is smaller than
W2
, we clamp to100%
, or one item per row. - When the screen width is larger than
W2
, we clamp to the firstclamp()
. - In that first clamp, when the screen width is smaller than
W1
, we clamp to100%/(M + 1) + 0.1%)
, or M items per row. - In that first clamp, when the screen width is bigger than
W1
, we clamp to100%/(N + 1) + 0.1%)
, or N items per row.
We made two media queries using only one CSS declaration! Not only this, but we can adjust that declaration thanks to the CSS custom properties, which means we can have different breakpoints and a different number of columns for different containers.
How many media queries do we have in the above example? Too many to count but we will not stop there. We can have even more by nesting another clamp()
to get from N
columns to M
columns to P
columns to one column. (😱)
clamp(
clamp(
clamp(100%/(var(--n) + 1) + 0.1%, (var(--w1) - 100vw)*1000,
100%/(var(--m) + 1) + 0.1%),(var(--w2) - 100vw)*1000,
100%/(var(--p) + 1) + 0.1%),(var(--w3) - 100vw)*1000,
100%), 1fr))
As I mentioned at the very beginning of this article, we have a responsive layout without any single media queries while using just one CSS declaration—sure, it’s a lengthy declaration, but still counts as one.
A small summary of what we have:
- ✔️ Only one line of code
- ✔️ Consistent element widths in the footer
- ✔️ Full control of the number of items per row
- ✔️ Items grow and shrink
- ✔️ Control when the items wrap
- ✔️ Easy to update using CSS custom properties
Let’s simulate container queries
Everyone is excited about container queries! What makes them neat is they consider the width of the element instead of the viewport/screen. The idea is that an element can adapt based on the width of its parent container for more fine-grain control over how elements respond to different contexts.
Container queries aren’t officially supported anywhere at the time of this writing, but we can certainly mimic them with our strategy. If we change 100vw
with 100%
throughout the code, things are based on the .container
element’s width instead of the viewport width. As simple as that!
Resize the below containers and see the magic in play:
The number of columns change based on the container width which means we are simulating container queries! We’re basically doing that just by changing viewport units for a relative percentage value.
More tricks!
Now that we can control the number of columns, let’s explore more tricks that allow us to create conditional CSS based on either the screen size (or the element size).
Conditional background color
A while ago someone on StackOverflow asked if it is possible to change the color of an element based on its width or height. Many said that it’s impossible or that it would require a media query.
But I have found a trick to do it without a media query:
div {
background:
linear-gradient(green 0 0) 0 / max(0px,100px - 100%) 1px,
red;
}
- We have a linear gradient layer with a width equal to
max(0px,100px - 100%)
and a height equal to1px
. The height doesn’t really matter since the gradient repeats by default. Plus, it’s a one color gradient, so any height will do the job. 100%
refers to the element’s width. If100%
computes to a value bigger than100px
, themax()
gives us0px
, which means that the gradient does not show, but the comma-separatedred
background does.- If
100%
computes to a value smaller than100px
, the gradient does show and we get agreen
background instead.
In other words, we made a condition based on the width of the element compared to 100px
!
This demo supports Chrome, Edge, and Firefox at the time of writing.
The same logic can be based on an element’s height instead by rearranging where that 1px
value goes: 1px max(0px,100px - 100%)
. We can also consider the screen dimension by using vh
or vw
instead of %
. We can even have more than two colors by adding more gradient layers.
div {
background:
linear-gradient(purple 0 0) 0 /max(0px,100px - 100%) 1px,
linear-gradient(blue 0 0) 0 /max(0px,300px - 100%) 1px,
linear-gradient(green 0 0) 0 /max(0px,500px - 100%) 1px,
red;
}
Toggling an element’s visibility
To show/hide an element based on the screen size, we generally reach for a media query and plop a classic display: none
in there. Here is another idea that simulates the same behavior, only without a media query:
div {
max-width: clamp(0px, (100vw - 500px) * 1000, 100%);
max-height: clamp(0px, (100vw - 500px) * 1000, 1000px);
overflow: hidden;
}
Based on the screen width (100vw
), we either get clamped to a 0px
value for the max-height
and max-width
(meaning the element is hidden) or get clamped to 100%
(meaning the element is visible and never greater than full width). We’re avoiding using a percentage for the max-height
since it fails. That’s why we’re using a big pixel value (1000px
).
Notice how the green elements disappear on small screens:
It should be noted that this method is not equivalent to the toggle of the display value. It’s more of a trick to give the element 0×0 dimensions, making it invisible. It may not be suitable for all cases, so use it with caution! It’s more a trick to be used with decorative elements where we won’t have accessibility issues. Chris wrote about how to hide content responsibly.
It’s important to note that I am using 0px
and not 0
inside clamp()
and max()
. The latter makes invalidates property. I won’t dig into this but I have answered a Stack Overflow question related to this quirk if you want more detail.
Changing the position of an element
The following trick is useful when we deal with a fixed or absolutely positioned element. The difference here is that we need to update the position based on the screen width. Like the previous trick, we still rely on clamp()
and a formula that looks like this: clamp(X1,(100vw - W)*1000, X2)
.
Basically, we are going to switch between the X1
and X2
values based on the difference, 100vw - W
, where W
is the width that simulates our breakpoint.
Let’s take an example. We want a div placed on the left edge (top: 50%; left:0
) when the screen size is smaller than 400px
, and place it somewhere else (say top: 10%; left: 40%
) otherwise.
div {
--c:(100vw - 400px); /* we define our condition */
top: clamp(10%, var(--c) * -1000, 50%);
left: clamp(0px, var(--c) * 1000, 40%);
}
First, I have defined the condition with a CSS custom property to avoid the repetition. Note that I also used it with the background color switching trick we saw earlier—we can either use (100vw - 400px)
or (400px - 100vw)
, but pay attention to the calculation later as both don’t have the same sign.
Then, within each clamp()
, we always start with the smallest value for each property. Don’t incorrectly assume that we need to put the small screen value first!
Finally, we define the sign for each condition. I picked (100vw - 400px)
, which means that this value will be negative when the screen width is smaller than 400px
, and positive when the screen width is bigger than 400px
. If I need the smallest value of clamp()
to be considered below 400px
then I do nothing to the sign of the condition (I keep it positive) but if I need the smallest value to be considered above 400px
I need to invert the sign of the condition. That’s why you see (100vw - 400px)*-1000
with the top
property.
OK, I get it. This isn’t the more straightforward concept, so let’s do the opposite reasoning and trace our steps to get a better idea of what we’re doing.
For top
, we have clamp(10%,(100vw - 400px)*-1000,50%)
so…
- if the screen width (
100vw
) is smaller than400px
, then the difference (100vw - 400px
) is a negative value. We multiply it with another big negative value (-1000
in this case) to get a big positive value that gets clamped to50%
: That means we’re left withtop: 50%
when the screen size is smaller than400px
. - if the screen width (
100vw
) is bigger than400px
, we end with:top: 10%
instead.
The same logic applies to what we’re declaring on the left
property. The only difference is that we multiply with 1000
instead of -1000
.
Here’s a secret: You don’t really need all that math. You can experiment until you get it perfect values, but for the sake of the article, I need to explain things in a way that leads to consistent behavior.
It should be noted that a trick like this works with any property that accepts length values (padding
, margin
, border-width
, translate
, etc.). We are not limited to changing the position
, but other properties as well.
Demos!
Most of you are probably wondering if any of these concepts are at all practical to use in a real-world use case. Let me show you a few examples that will (hopefully) convince you that they are.
Progress bar
The background color changing trick makes for a great progress bar or any similar element where we need to show a different color based on progression.
This demo supports Chrome, Edge, and Firefox at the time of writing.
That demo is a pretty simple example where I define three ranges:
- Red: [
0% 30%]
- Orange: [
30% 60%]
- Green: [
60% 100%]
There’s no wild CSS or JavaScript to update the color. A “magic” background property allows us to have a dynamic color that changes based on computed values.
Editable content
It’s common to give users a way to edit content. We can update color based on what’s entered.
In the following example, we get a yellow “warning” when entering more than three lines of text, and a red “warning” if we go above six lines. This can a way to reduce JavaScript that needs to detect the height, then add/remove a particular class.
This demo supports Chrome, Edge, and Firefox at the time of writing.
Timeline layout
Timelines are great patterns for visualizing key moments in time. This implementation uses three tricks to get one without any media queries. One trick is updating the number of columns, another is hiding some elements on small screens, and the last one is updating the background color. Again, no media queries!
When the screen width is below 600px
, all of the pseudo elements are removed, changing the layout from two columns to one column. Then the color updates from a blue/green/green/blue pattern to a blue/green/blue/green one.
Responsive card
Here’s a responsive card approach where CSS properties update based on the viewport size. Normally, we might expect the layout to transition from two columns on large screens to one column on small screens, where the card image is stacked either above or below the content. In this example, however, we change the position, width, height, padding, and border radius of the image to get a totally different layout where the image sits beside the card title.
Speech bubbles
Need some nice-looking testimonials for your product or service? These responsive speech bubbles work just about anywhere, even without media queries.
Fixed button
You know those buttons that are sometimes fixed to the left or right edge of the screen, usually for used to link up a contact for or survey? We can have one of those on large screens, then transform it into a persistent circular button fixed to the bottom-right corner on small screens for more convenient taps.
Fixed alert
One more demo, this time for something that could work for those GDPR cookie notices:
Conclusion
Media queries have been a core ingredient for responsive designs since the term responsive design was coined years ago. While they certainly aren’t going anywhere, we covered a bunch of newer CSS features and concepts that allow us to rely less often on media queries for creating responsive layouts.
We looked at flexbox and grid, clamp()
, relative units, and combined them together to do all kinds of things, from changing the background of an element based on its container width, moving positions at certain screen sizes, and even mimicking as-of-yet-unreleased container queries. Exciting stuff! And all without one @media
in the CSS.
The goal here is not to get rid or replace media queries but it’s more to optimize and reduce the amount of code especially that CSS has evolved a lot and now we have some powerful tool to create conditional styles. In other words, it’s awesome to see the CSS feature set grow in ways that make our lives as front-enders easier while granting us superpowers to control how our designs behave like we have never had before.
There’s some clever stuff going on here, but…
Maybe it’s too clever?
Sometimes writing more expressive, readable code is better. Especially in larger teams, or teams with a range of abilities/skills.
Media queries are self documenting.
I think some of the examples above would need substantial comments to explain the logic, and that kinda defeats the object of writing less code.
But that’s just my (humble) opinion. ;)
The goal here is not to get rid of media queries or completely replace them. I am exploring different techniques/ideas that allow you to have conditional CSS based on screen (or container) width.
At the end of the article you will have, in addition to media queries, more tricks in hands and it’s up to you to use them correctly.
I will not advise you to make a spaghetti code with clamp() everywhere but in some cases you have the ability to replace two (or more) media queries with one clamp() that you can adjust using CSS variables. To this, you add a few comments next to the CSS variables and your code is perfect ;)
You said “Media queries are self documenting.” and this is because they have been used since more than 10 years. I am suggesting “new” tricks and anything new is not always easy to digest. Actually, when people find a clamp() in the code they are a bit surprised but in the future it will become something trivial and by simply looking into the code we can easily understand what is going there ;)
Again, I am not here to tell you “don’t use media query”. I am here to tell you “hey, you can also do it that way without media query” :)
Thanks for the article! That is exactly what I would expect from a website called “CSS Tricks” ;)
All this is a great example of CSS creative mastery, however I agree with Kev, that it may be extremely hard to reverse engineer your code without the step-by-step guidance that you provided :)
Anyway, as a person who loves that magic nature of CSS, I really enjoyed it!
I completely agree with the “expressive, readable code” but in this case you could definitely make a SASS mixin out of it and make it nice for your fellow developers.
I have to agree with Kev on this one. I wouldn’t use this, since media query/container query are intended for this behavior, where clamp is not.
Nevertheless I enjoyed this article. It is a cool hack to tryout and good to know that it exists but not to use in production code.
Too clever for Safari in a few examples above… but it will learn given time
What I really like about this is that it keeps the responsiveness within the style rule.
Too often you see media query/queries ‘attached’ to a style rule get totally divorced from the style rule in the code, especially with older codebases.
This gets even worse when someone (cough) decided to merge all the responsive css for different elements into a single breakpoint media query to minimize the number of repetitions of the same media query and overall CSS size.
For good intentions, but pain in the ass to work with and best suited to build tools/plugins like postcss-combine-media-query
Exactly! and in addition to the responsiveness being within the style rule, we can easily adjust it using CSS variables which give us the ability to have different responsive behaviors for different elements without duplicating any code ;)
To quote Private Frazer from Dad’s Army, “We’re doomed”
Container queries will come, We’ll all say “hallelulah”, Webkit will delay implementation long enough to prop up the App Store a bit longer, squirrels will manically update npm packages and dependencies, things will break and get fixed, polyfills will multiply and everyone will rally under the new code on the block.
In the meantime there’s your solution. I just can’t think of an appropriate atomic class name to avoid repetition.
Amazing article, and I like that you explain the formulas.
I strongly prefer this to media queries, though the formulas should always be well commented or the meaning might be lost. I don’t know if I trust most programmers to even bother with that.
please god bring sub grid to all browsers just to make things easier. What are they waiting for?
Thanks for this awesome exploration! This is really high quality edge content
Great post!
I would though split those very long complicated CSS lines into a variables with meaningful names
This is wonderful!
By following along, it was simple for me to see how I could do away with Bootstraps grid layout. In a world of trying to make code smaller this eliminates the need to import that one last piece with some small additions.
Thanks for this great article I learnt a lot from it,
I think this way of responsiveness make reading css harder. with media query we have exact breakpoint pixel and any body can understand without reading the code.
I have to disagree here:
“with media query we have exact breakpoint pixel” –> I also have exact breakpoint pixel here the same way media query do. I am simulating the same behavior of media query with less of code.
“and any body can understand without reading the code.” –> you say this because you know media queries since too long and media queries are available since more than 10 years now. The fact that media queries are widely used make them “easy” but still no anyone can understand them at first glance. You have no idea the number of people that get confused between min-width/max-width or the syntax of media query or the order of media queries. let’s not talk about the specificity issues. You still need to read the DOC of media query to understand them, they are not intuitive.
My logic is “easier” than media query BUT it’s something new and anything new always seems hard because we are not used to it. We need to give it time and if people start to work with it will be “easy” because such code will be widely used and documented. Let’s not forget the fact that my logic rely on CSS variable so all you have to do is to update those variables. If they are well documented, you don’t even need to check the code. We cannot say the same for media queries
I found when trying the Responsive Card example that if the viewport width is equal to the
--w
custom property value, you won’t get the desired outcome of all properties toggling between minimum and maximum clamp values. When they’re equal,--c: (100vw - var(--w))
is 0px therefore the value of bothvar(--c)*-1000
andvar(--c)*1000
is the same, 0px, and the minimum clamp value is used for them all instead of one changing to the max value and the other changing to the minimum value.It seems this can be avoided by using a value that can never be equal to the the viewport width. That is, use a non-whole number like
--w: 450.1px;
. Alternately, add a tiny percentage, like--c: (100vw - var(--w) + .1%)
; that might be preferable so the “breakpoint” value remains a nice, round number.What about the exact 450px on Responsive card example? https://codepen.io/t_afif/pen/abyLYGy the layout is broken.
You can avoid such issue by using values like 450.05px or 450.99px. A value that the browser cannot use it (or it’s rare to be used) as width
Hi, is there any way to center divs when they are wraped to another row?
In this codepen, they aren’t centered. https://codepen.io/t_afif/pen/bGqbgYY
Unfortunately, this won’t be possible with such configuration and CSS grid in general. You will need to try something else using Flexbox.
Actually I don’t see how to combine the responsiveness trick with centering.
