Changing text selection colours

A nice little trick to add a bit of polish to your site is changing the colour of text selection. Stockapps Blog have a nice orange colour, and of course, Si Digital have their well known Fuchsia highlighting.

You can easily implement this using the pseudo-element ::selection.

::selection {
    color: white;
    background: red;
}

Unfortunately, Gecko requires prefixing, so you also have to add in ::moz-selection:

::moz-selection {
    color: white;
    background: red;
}
::selection {
    color: white;
    background: red;
}

It is worth noting that this is experimental, having been dropped from the specification, so I guess you shouldn't rely on this for anything "important" just yet. Hopefully it will stick around!
