Code:
::selection { background: #fff; color: #4472B9; }
::-moz-selection { background: #fff; color: #4472B9; }
If it is not in your stylesheet and you'd like to add it to your index file, you'd simply do this:
Code:
<style>
::selection {
background: #fff;
color: #4472B9; }
::-moz-selection {
background: #fff;
color: #4472B9; }
</style>
Hope I could help.
