[00:00] Okay, CSS has some fundamental concepts called like the box model or whatever. It's width and height. Okay, everything on the web is a rectangle. So every element's a rectangle. And you can control it and you can push away other rectangles with margin. [00:13] And you can push inwards on your elements with padding. And then there's a border. And then there's an outline. But the outline's not part of the box model. All this fundamental stuff that you know. But then all of a sudden, not so long ago, we got names for all these things like margin [00:28] and padding and border and these things that they're called logical properties. So instead of saying padding left, we have padding inline start. And for a lot of us that just, you know, are English speaking people making English websites, those two things are synonymous [00:43] and they do the exact same thing. But we are told like, hey, maybe it's smarter if we use padding inline start instead of padding left, because they are actually a little bit different. The idea is that it's padding along the direction of where the text starts.
