How to define specific CSS rules for IE9 alone?

Question

Friends, please help me in defining specific css rule for IE9? For example like this

/* IE 6 fix */
* html .twit-post .delete_note a { background-position-y:         


        

Answer 1

You can prepend the CSS style with

:root

to make it IE9-specific, like this:

:root #element { color:pink \0/IE9; }  /* IE9 */
