 I'm sure you've had a container look something like this without a border, but this is a bunch of CSS that we could actually simplify and just do a width and use some modern CSS. So I could actually say 100% minus two REM, so it's one REM on each side. And just doing that, you'll notice that it's off the side there. And so we can fix that by saying a margin inline, which is only going to do the left and the right one. So I don't reset on the top and the bottom. And now you can see that's always staying centered, but we do have the problem of it, and we need a max width on there, but because we're using a min width on here, I can just come, put a comma, and then set the same thing we had before, which was 600 pixels and hit save on there. And now we have exactly what we had before, where we have all that spacing around, it grows, it shrinks, everything works really well, and with just two lines of CSS.
