* PE to use SVG as CSS background image with fallback for IE8/7/6 | |
* | |
* Using SVG as CSS background image to display | |
* resolution-independent logos or icons is pretty | |
* awesome but does completely fail on IE8/7/6 | |
* | |
* The trick: | |
* All three IE versions don't support rgba color values. | |
* By defining a rgba background color together with the | |
* SVG background image for all modern browsers, IEs prior | |
* to IE 9 will automatically ignore that and switch to the | |
* first background definition, where you can add a fallback | |
* png with the same size for example. | |
* | |
* Tested in: | |
* Safari 5.1+ | |
* Chrome 16 | |
* Firefox 9+ | |
* Opera 11.6+ | |
* MobileSafari on iOS 5 | |
* IE6, IE7, IE8, IE9 | |
* | |
* General support for SVG backgrounds: | |
* http://caniuse.com/#feat=svg-css | |
* | |
* Known issues: | |
* - Does not work in Firefox < 4 | |
* - Might not work on older versions of Android Browser | |
* | |
* Thoughts? | |
* Please reply on Twitter: @bastianallgeier | |
* Or comment on this gist on Github. | |
* | |
* Awesome mod by @jng5 to demonstrate the resizability: | |
