You can use this style. this will work on all major browser except IE

<style>
             ::-moz-selection
            {
             background:#0C0;
             color:#f00;
             }
            ::selection
            {
            background:#6374AB;
            color:#F00;
           }
    </style>

In Firefox, you can apply CSS styles to ::-moz-selection.
In Safari, you can apply CSS styles to ::selection.
