title: Asp.net webpage has a lot of blank space at bottom
body: <p>My asp.net webpage has a ton of white space at the bottom of a div within a content page, and I have no idea where its coming from.  There are NOT a ton of
  <code>&lt;br /&gt;</code>
  's or &amp;nbsp's in the source view.  How can I find out where the space is coming from and correct?</p>
  
  <p>Could this element be taking up space???</p>
  
  <pre><code>   &lt;ul style="display: none; visibility: hidden; z-index: 10000; overflow-x: hidden; overflow-y: auto; width: 246px; position: absolute; height: 320px;" class="ajax__combobox_itemlist" id="ctl00_ctl00_PageContent_PageContent_cboTurnOver_OptionList"&gt;&lt;li&gt;&amp;nbsp;&lt;/li&gt;&lt;li&gt;Aaron Ament - 034  &lt;/li&gt;&lt;li&gt;Aaron Stack - 235  &lt;/li&gt;&lt;li&gt;Accounting  - OA   &lt;/li&gt;&lt;li&gt;Adam Kauth - 289  &lt;/li&gt;&lt;li&gt;Admin  - 481  &lt;/li&gt;&lt;li&gt;Aimee Tatge - 149  &lt;/li&gt;&lt;!--Over 100 entries removed for security and brevity--&gt;&lt;li&gt;Zeddie Roshelle - 346  &lt;/li&gt;&lt;/ul&gt;
