Builtins

The standard library of Simple CSS (the spec, 41).

class MMO\client\scs\Builtins

Namespace: MMO\client\scs

It stays deliberately small: anything css can already express at runtime (`calc`, `clamp`, `min`, `max`, `var`, ...) is **not** evaluated but emitted as written -- see [`Parser::CSS_FUNCTIONS`](https://mcp.mmoframework.fr/documentation/mmo.client/php/scs/Parser.md#parser-css-functions). Everything here is a compile-time value generator instead.

Builtins::Call('darken', [Value::Ident('#6366f1'), Value::Number(10, '%')]); // #4f51ed
