Some nice coverage from Andy about CSS things that are truly new. If you haven’t looked at new things in CSS in, say, a year, I’d bet pretty much all of this will be new to you. A lot of it is cutting-edge enough that you might not be able to get it into projects immediately, but that gap is getting pretty short these days. Rough guess, I’d say a year and we’ll be using all this stuff without much thought.
- Masonry layout (e.g.
grid-template-rows: masonry;) which I think was a terribly clever way to approach this long-awaited feature.. - The
:isselector which makes certain selectors way less obnoxious to write (e.g.article :is(h1, h2, h3):not(:first-child)). This makes me wonder why we never had such a thing in Sass that helped with that. - Functions like
min(),max(), andclamp(), and I think the best practices and clever uses for them are just shaking out. Fluid type is the most obvious and useful example, but only scratches the surface. - Units like
chandex. I really likemax-width: 70ch;. There’s a general bit of typography advice that line length should be between 45 and 75 characters long (I made a bookmarklet to test it once), so rather than forcing that with some abstractly relatedwidth, you use the actual width of characters as the width. - Fancy
text-decoration(e.g.text-decoration-thickness: 0.5rem;) meaning we can thicken up an underline without giving up the usefulness that istext-decoration-skip-inklike we would if we had to resort to aborder.)
A note: 70ch will not give you the width of 70 successive characters, even in monospace – there is space between each character. Learned this when trying to perfectly size an input for a number of constant length.
