Respond.js is a fast, lightweight JavaScript polyfill that adds min/max-width CSS3 Media Query support to browsers lacking it, primarily Internet Explorer 6-8. It enables responsive web designs in legacy browsers by fetching CSS via AJAX and translating media queries.
Use cases
- support responsive layouts in internet explorer 8
- polyfill css3 media queries for legacy browsers
- make mobile-first responsive design work in ie6-ie8
- enable min-width and max-width media queries in old ie
- serve responsive css to browsers without media query support
When to choose
- you must support IE 8 or older browsers that lack CSS3 media query support
- you need a tiny (1kb gzipped) dependency-free polyfill for responsive breakpoints
- you are maintaining a legacy site with mobile-first responsive CSS
When to avoid
- your target browsers natively support CSS3 media queries (all modern browsers)
- you need media query features beyond min/max-width
- your stylesheets are on a CDN and you cannot set up a local proxy for cross-domain AJAX
- you are starting a new project - IE 6-8 support is obsolete
