Button Effect for Text Links

I just implement this technique on my blog, maybe some of you already have noticed that when you click a link in this blog it will give you an effect like you press it, just like pressing a real button or a "bump down". Actually I read this in Chris Coyier blog CSS-Tricks, and after reading I said why not implement this one?. I loved the effect maybe my blog readers will also loved this one and hopefully it can encourage more clicks ;-).

So to make this possible all you to do is to add this simple CSS codes:
a:active {

*Note a:active refers to all links in your blog, if you don't want to implement this in all of your link you can add class or id.
*If you don't know how to find CSS code please refer to my other tutorials.
