Linear-gradient not working in IE 11

Question

I have a css rule that works fine in chrome, firefox and used to work in IE. Now my seemingly valid css is not working.

.s-tour {
/*border-radius: 5px;*/
mar         


        

Answer 1

So the problem I really had was that I was not telling IE to render the page using the latest standards of css. Adding to the block fixed most of my problems.
