#FPWD

The @w3c #CSS #WorkingGroup has published 'CSS Functions and Mixins Module' as #FPWD #timetogiveinput

To reduce repetition and promote consistency, #developers use CSS pre-processors to create reusable macros. This module introduces functions (enabling authors to create parameterized features similar to custom properties) and mixins that are functions operating at the style rule level.

Feedback welcome! https://github.com/w3c/csswg-drafts/labels/css-mixins-1

Snapshot of lines of code showing a simple custom function to negate a value:

@function - - negative(- - value) {
result: calc(-1 * var(- - value));
}

Then, that function can be referenced with - - negative() in some declarations:

html {
- - gap: 1em;
padding: - - negative(var(- - gap));

or by passing the value explicitly, like:

padding: - - negative(1em);
}

Two existing @w3c specifications are published under a new level. #FPWD #timetogiveinput
