My Footer Is floating up to a page

[joeleearts]

I created a site having it this

<div class="wrapper">
  <div class="content_wrapper">
     <div class="content"></div>
     <div class="sidebar"></div>
  </div>
</div>

<div class="footer"></div>

that is how it is on my local and all is working perfectly but when it was uploading online the footer was jumping to the center of the page, i added a "clear:both " to the footer it doesn't work, then i added a div and clear it below after the closing tag of the wrapper. still not working.

do your page has just these two div "wrapper" and "footer"?
