This is a jfiddle
This is the result:

I want the circled div to be at the bottom of the purple div.
The circled div is this div
<div class="slNewClass">
                     <div class="details">
                         <span class="content">Service Level</span>
                         <span class="value" id="slSpan" runat="server">0%</span>
                     </div>
                 </div>
