I was wondering the same thing and came across this response from Code Academy:

From the sounds of it, this used to be a caution in old timey web development, like 15-20 years ago. So the warning still exists in some editors today, but it’s really nothing to worry about!

Elementor is giving me this warning: The universal selector (*) is known to be slow.

Some insight into the above 2 points would be appreciated. Thank you in advance.

You could do something like this:

Or, if the container starts in the middle of the page and you want it to stick when it reaches the top, here’s an example (though you’ll need JavaScript):

An Explanation of How the Intersection Observer Watches

I pretty sure you just mistyped, but it says it needs to be set ‘along’ a baseline. This means that the element that you want to vertically align needs a surrounding element with which to align itself with in some way. For instance, if you have an inline <img> element (image element) within a <p> element (paragraph element), the text of the paragraph would be considered a baseline that you can vertically align the image with. You can’t simply stick an image inside of a <div> element and then try to move the image within that element with the vertical-align property. It won’t do anything. Now if you did:

<div>
  Hello World! 
  <img>
</div>

You use the text ‘Hello World!’ as a baseline around which you align your img. This is an old question, I know, but hopefully this helps someone in the future.

alone should be along

Even with the example, for people learning CSS, this sentence does not make sense. The problem is not what baseline means, its the grammar of the sentence that throws everything off.

Can you please explain?

How come the property name is vertical-align and a few of the property values starts with text ( text-top, text-bottom )

What a naming convention :(
