The CSS Working Group has published an updated Working Draft of CSS Custom Properties for Cascading Variables.
The Variables spec defines a family of “custom” properties, whose names and values are completely author-defined. These properties provide values to “CSS variables”, a new type of value, which are substituted with the values they stand for, allowing authors to create more modular and maintainable style sheets by centralizing the definition of common values.
We’d appreciate people to review this draft carefully, as we expect to take it to Last Call soon. In particular, the section on the variables API is new, and we would appreciate feedback on it.
Significant changes are listed in the Changes section.
As always, please send feedback to the (archived) public mailing list www-style@w3.org with the spec code () and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
