Custom properties and @property

Permalink | in CSS for JavaScripters

You’re reading a failed article. I hoped to write about @property and how it is useful for extending CSS inheritance considerably in many different circumstances. Alas, I failed. @property turns out to be very useful for font sizes, but does not even approach the general applicability I hoped for.

Inherit, initial, unset, revert

Permalink | in CSS for JavaScripters

Today we’re going to take a quick look at a few special CSS keywords you can use on any CSS property: inherit, initial, revert, and unset. Also, we will ask where and when to use them to the greatest effect, and if we need more of those keywords.

The first three were defined in the Cascading Level 3 spec, while revert was added in Cascading Level 4. Despite 4 still being in draft revert is already supported. See also the MDN revert page, Chris Coyier’s page, and my test page

aspect-ratio is currently supported by Chrome 90, by Firefox 88 with the correct flag enabled, and by Safari Technology Preview. I tested mostly in the first two — for complicated reasons I cannot install STP right now, but a kind Twitter follower sent me a few screenshots. It behaves as Chrome.

Two options for using custom properties

Permalink | in CSS for JavaScripters

Recently I interviewed Stefan Judis for my upcoming book. We discussed CSS custom properties, and something interesting happened.

We had a period of a few minutes where we were talking past one another, because, as it turns out, we have completely opposite ideas about the use of CSS custom properties. I had never considered his approach, and I found it interesting enough to write this quick post.

fit-content and fit-content()

Permalink | in CSS for JavaScripters

Today we will look at fit-content and fit-content(), which are special values for width and grid definitions. It’s ... complicated — not as a concept, but in its practical application.
