css - Divs with 2 columns in a vertical column -

-

i'm trying make column div's 1 after another, each div split 2 columns..i've managed tells me it's not semantic...so if take , tell me how code better?

http://jsfiddle.net/synqp/1/

    <body>          <div id="wrapper">          <div id="lt">          <div id="bl">             <p>column 1</p>         </div>          <div id="br">             <p>column 2</p>         </div>          <p><br>&nbsp;</p>          <div id="bl">             <p>column 1</p>         </div>          <div id="br">             <p>column 2</p>         </div>           </div>            <div id="rt">        <p>123</p>         </div>       </div>      </body> 
@import url("reset.css");  body { font-family: verdana, arial, helvetica, sans-serif; font-size: 14px; color:#000; }  #wrapper { margin: 0 auto; width: 960px; padding: 4px; background-color: #999; height: 600px; }  #lt { background: #33ccff; width: 400px; float: left; background-color: #333; height: 600px; }  #rt { float: left; background: #ffffff; width: 560px; }  #bl{ float:left; width:120px; height:120px; background:#fff333; } #br{ float:left; width:280px; background:#e4e4e4; height: 120px; }

a few improvements:

  • instead of: <p><br>&nbsp;</p> use proper css-margins like: margin-bottom: 20px;
  • you have multiple ids same name, ids must unique, use classes instead!
  • use semantic names: instead of br write block-right
  • floats can problematic, don't need be. using display: inline-block may alternative
