wrap h2 within a anchor tag or anchor tag within a <h2>tag like  <a  id="abc" href="#"> <h2>...</h2></a>
you can give some id to anchor tag or h2 it will help you in doing a styling or just in case u want to use some js.
and if you are doing it with css means
a:active should work,,but do check cross browsers and w3schools will be very handy :)
