title: How to make a Google Scripts like UI
body: <p>I am trying to make an extension for the Google Drive app. My app will be hosted on Google app engine and I would like to keep the UI design as close to the default Google styling as possible. 
  I've tried using the dev tools to get a better understanding of the way the page looks but because pretty much all of it is dynamic and coded in JS it's hard to get an accurate understanding.</p>
  
  <p>What I would like to know is if there is some sort of library or framework I could use to create a standard looking Google Drive editor similar to <a href="http://i.stack.imgur.com/bERKz.png" rel="nofollow">this one</a></p>
