In general, I think “all” methods are allowed, or acceptable at least, but my original question was if there is a current “standard”, a method that is the best (although I realize there’s no perfect one solution).
Obviously, my favorite solution (using overflow:hidden) doesn’t work when I actually don’t want the container to hide the overflowing stuff (or show drop shadows — I hadn’t even thought of that!). But then I usually go to float:left. And if I don’t want my container to float either, that’s when I use content:”” methods. I guess in the end it depends on the situation, but I was still wondering if there is a method that’s simply the best choice in most situations, or if there’s a general “try this first, then try that, then try that” structure nowadays.
