Forcing IE9 to render as IE8, but still using CSS3 properties

I'm using <meta http-equiv="X-UA-Compatible" content="IE=8"> to make IE9 render as IE8. This has fixed a lot of my issues, however because IE8 doesn't have support for box-shadow I was forced to use filter: progid:DXImageTransform.Microsoft.Shadow(color='#333333', Direction=145, Strength=5); to get a similar effect to my shadow. Now, IE9 does have support for box-shadow however i can't get IE9 to use box-shadow instead of the filter.

Does anyone know how to get IE9 to render the shadow?

Why are you forcing it to render as IE8 then expecting it to render as IE9? :) IE8 didn't have box-shadow support, so IE9 dutifully disables it when it's rendering as IE8.

If you want IE9 to render the box-shadow you'll have to set it back to rendering as IE9 or EDGE. If you are forced to maintain the x-ua-compatible as it is, then you'll have to use filters.

Note there's different syntax for IE8...

/* For IE 8 */
-ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Strength=4, Direction=135, Color='#000000')";
/* For IE 5.5 - 7 */
filter: progid:DXImageTransform.Microsoft.Shadow(Strength=4, Direction=135, Color='#000000');

(example grabbed from http://robertnyman.com/2010/03/16/drop-shadow-with-css-for-all-web-browsers/)

Because these are pretty nasty ideally I'd suggest you isolate them in an IE-only stylesheet delivered with conditional comments.

You can't make IE9 use its native box-shadow if it's in IE8 mode.

You can:

  • Just use IE9 mode and fix your page to work in it - this is what I'd do.
  • Use CSS3 PIE - it can simulate box-shadow in IE6-8.
