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
