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  • you are starting a new project - IE 6-8 support is obsolete
