internet explorer 8 - How can I get IE8 to accept a CSS :before tag?

Question

I have the following CSS code

.editable:before {
    content: url(../images/icons/icon1.png);
    padding-right:5px;
}

this is used in conjunction with the following markup:

<span class="editable"></span>

In every other blessed browser in the world my icon is appearing, but IE8 seems to have a problem with this. Isn't the :before pseudo-element CSS2? isn't content: also a CSS2 command? what gives?

Answer 1

Actually you should be careful here and read the detail. For full details, see this link - which states

In Windows Internet Explorer 8, as well as later versions of Windows Internet Explorer in IE8 Standards mode, only the one-colon form of this pseudo-element is recognized—that is, :before. Beginning with Windows Internet Explorer 9, the ::before pseudo-element requires two colons, though the one-colon form is still recognized and behaves identically to the two-colon form.

Meaning for browsers <IE9 - you must use :before and for >=IE9 - you must use ::before
