title: Styling twitter bootstrap buttons
body: <p>Twitter-Bootstrap buttons are awesomely beautiful. <a href="http://getbootstrap.com/components/">Try them out by scrolling over them</a></p>
  
  <p><img src="https://i.stack.imgur.com/2SQ0p.png" alt="bootstrap button screenshot"></p>
  
  <p>But they are limited in colors. </p>
  
  <p>Is there any way I could change the base color of the button while keeping the beautiful hover-over effect that bootstrap has made so beautiful and effortless?</p>
  
  <p>I am completely unaware of what the css/javascript looks like that twitter uses to maintain those effects.</p>
