CSS for Mobile/Responsive Design – IE Hacks

I’m testing on IE11, which is supposed to be standards compliant. And it is, except when it isn’t. Here is a great example of a hack that I had to use to make some sweet JQuery Superfish menu items behave in IE11.

#superfish-1 {
font-size: 98.9%;
float: left;
margin: -75px -86px 15px;
padding: 0 0 7px 58px;
position: relative;
}
@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
/* IE10-specific styles go here */
#superfish-1 {
font-size: 93%;
float: left;
margin: -77px -86px 15px;
padding: 0 0 7px 58px;
position: relative;
}
}
