Sizzle is a pure-JavaScript, bottom-up CSS selector engine designed to be dropped into a host library, historically serving as jQuery's selector engine. It supports virtually all CSS3 selectors with results returned in document order across a wide range of browsers.
Use cases
- add CSS selector querying to a custom JavaScript library
- support CSS3 selectors in legacy browsers like IE7
- parse and match complex CSS selector expressions in the DOM
- build a DOM manipulation library without writing a selector engine
- query DOM elements with selectors like :not(a.b) and nested pseudo-selectors
When to choose
- you need a standalone selector engine for a host library or legacy browser support
- you're maintaining or building on top of jQuery-era tooling
When to avoid
- you're targeting modern browsers only - native querySelector/querySelectorAll covers this
- you need a full DOM manipulation library - use jQuery instead
