title: Jquery If statement to check margin left of div to apply opacity to a separate id
body: <p>I've been trying to tweak things a bit to get this to work and so far I haven't been able to use jquery to check a <code>div</code>'s left margin and on the condition it is in the <code>left: 0px</code> position, to output whatever action, in my case to apply opacity to a separate div. Here's my <a href="http://jsfiddle.net/K8CMp/3/" rel="nofollow">jfiddle</a>. In the jfiddle I want to check the gray div "trim", and on the condition it has <code>marginLeft: 0px</code>, to apply the opacity to the div "l1". Let me know if I need to explain this more.</p>
