title: Support 'background-size' property on older browsers?
body: <p>Is there a way that I can use the CSS3 'Background-Size' property and then use something like Modernizr to ensure that it's supported in older browsers (in particular I want to use 'background-size: cover' option)?</p>
  
  <p>I took a look at cssFx, which is mentioned from the Modernizr website, but this only seems to add vendor prefixes for browsers which need them to use a property, rather than allowing browsers such as IE8 to support the background size property.</p>
  
  <p>Also looked at CSS3Pie, but that doesn't seem to currently support the background-size property.</p>
