I’ve been using the colorzila tool to generate some css gradients. They work in all browsers I test in save for IE9; haven’t tried the other IE’s yet.
They have an IE checkbox on their UI. When I set it to on, the gradient sample no longer has a gradient; it defaults to the base solid color.
I thought it should work in IE since they do include the following css function
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#221f1f', endColorstr='#221f1f',GradientType=1 ); /* IE6-9 */
They have a button under the css called
IE9 Support (?)
Make sure you check that and follow the instructions that appear.
