An IE behavior (.htc) polyfill that adds support for the CSS3 background-size 'cover' and 'contain' values to Internet Explorer 8. It emulates the feature by inserting and positioning an <img> element behind the styled content.

Use cases

  • make background-size cover work in ie8
  • polyfill css background-size contain for old internet explorer
  • fix broken backgrounds in ie8 without huge images
  • support cover backgrounds on legacy browsers
  • progressive enhancement fallback for ie8 css3 backgrounds

When to choose

  • you must support IE8 and rely on background-size cover/contain
  • maintaining a legacy site that still targets old IE

When to avoid

  • you don't need to support IE8 or older IE browsers
  • you need multiple backgrounds, repeat values, or full background-size fidelity
  • starting a new modern project
