title: Setting container height based on container width and multiply by a constant
body: <p>I am attempting to set the height of a container based on its width multiplied by .75.</p>
  
  <p>I've come up with this but not sure where I've gone wrong because it doesn't work:</p>
  
  <pre><code>$('#slideContent').load(function() {
              var wide = ('#slideContent').width()
            $(this).css('height', $(this).width( wide * 0.75 ));
          });
  </code></pre>
  
  <p>Any advice?</p>
  
  <p>Thanks</p>
