Crate simplecss

A simple CSS 2.1 parser and selector.

This is not a browser-grade CSS parser. If you need one, use cssparser + selectors.

Since it’s very simple we will start with limitations:

Limitations

• At-rules are not supported. They will be skipped during parsing.
• Property values are not parsed. In CSS like * { width: 5px } you will get a width property with a 5px value as a string.
• CDO/CDC comments are not supported.
• Parser is case sensitive. All keywords must be lowercase.
• Unicode escape, like \26, is not supported.

Features

• Selector matching support.
• The rules are sorted by specificity.
• !important parsing support.
• Has a high-level parsers and low-level, zero-allocation tokenizers.
• No unsafe.
