title: How to change the css style of a button after the mouse release of the :active pseudo class?
body: <p>I would like to ask if there's a way to change the style of an element (like a button) immediately after the :active pseudo-class, that is immediately after the user has released the mouse click on that element, like they do on "Facebook" in the "Sign Up" button (<a href="https://www.facebook.com" rel="nofollow">https://www.facebook.com/</a> just try to click on it and then when you release the mouse you'll see the button become white in the background. 
  Is it possible with css or should I use JQuery? How can I do that?</p>
