CSS Properties Index

Published on Mar 27, 2008 (updated Jul 5, 2019), filed under development (feed). (Share this on Mastodon or Bluesky?)

A list of all CSS properties and their initial values. Note announcement and comments as well as the complementary HTML elements index.

The “living CSS” part of this index (“CSS 3/CSS”) is not being maintained anymore. For the latest in CSS, consider W3C’s properties list. If you like to study a similar overview of CSS in a book, consider Rote Learning HTML & CSS (2024).
