title: Responsive Canvas in Bootstrap column?
body: <p>I'm new to bootstrap and working on a project to help figure it out. I also don't know much LESS yet.</p>
  
  <p>I have 2 columns: col-xs-3 and col-xs-9. In the 9 column, I have a canvas that I would like to retain a particular aspect ratio. I don't actually care what the aspect ratio is, as long as it's the same everywhere. Specifically, as wide as the column and a proper height for the given width.</p>
  
  <p>I've tried using percentages for width and height, but even if that did work, it'd be less than ideal in a dynamic height column.</p>
