title: Are there any multi screen size/aspect-ratio libraries for web developers?
body: <p>There are many different viewing devices nowadays. Monitors, netbooks, slates, mobile phones, TVs, etc. and even within each of those categories they vary in size, resolution, aspect ratio, etc.</p>
  
  <p><strong>So my question is:</strong>
  Are there any libraries for web developers with intelligent restructuring of viewable elements on the page depending on screen size, resolution, and aspect ratio? A sort of write once view by all screens kind of library?</p>
