Crate use_css 

use-web-css

Small CSS utility primitives for RustUse.

Experimental

use-web-css is experimental while the use-web workspace remains below 0.3.0. Expect small API adjustments during the first release wave.

The published package name is use-web-css so it avoids the existing crates.io collision on use-css, while the Rust library target remains use_css.

Example

use use_css::{extract_css_declarations, is_css_color_value, minify_css_basic};

let declarations = extract_css_declarations(".card { color: red; margin-top: 1rem; }");

assert_eq!(declarations.len(), 2);
assert!(is_css_color_value("#ff00aa"));
assert_eq!(minify_css_basic(".card { color: red; }"), ".card{color:red;}");

Scope

• Lightweight CSS detection and declaration parsing.
• Small helpers for identifiers, custom properties, colors, and lengths.
• Comment stripping and basic minification.

Non-goals

• Full CSS parsing.
• Cascade engines.
• Browser style engines.
• CSS-in-JS utilities.
