line wont display on top of background color(css problem)

Setting line won't appear on top of the background color,what seems to be the problem?Th开发者_如何学Cank you.I have this code

<div class="setting-wrapper">
  <div class="setting-line"></div

   </div>

css

 .setting-wrapper{
  background-color:#E2E9E9;
  position: absolute;
  left:450px;
  top:20px; 
  border:1px solid #dedede; 
  display:block;
  width:500px;
  height:400px;
  -moz-border-radius:5px;
  -webkit-border-radius: 5px;
  border-radius:5px;
   }
  .setting-line{
margin-top:5px; 
margin-bottom:5px;
width:500px;
   border-top:solid #e6e6e6 1px;
   }

If <div class="setting-line"></div isn't a copy/paste typo, then theres a missing bracket at the end of the closing DIV.

But maybe it's only hard to see a difference between #E2E9E9 and #e6e6e6 (depending on the systems color-depth and/or screen capabilities).
