Looks like your pasted it in incorrectly. Your code looks like this and you're missing some targeters and brackets in the CSS.

  #main {
    width:481px; float:left; background:#fff; }
    html>body #main {width:485px; float:left; background:#fff; } 
    background:#fff url("http://www.blogblog.com/rounders/corners_main_bot.gif") no-repeat left bottom;
    margin:15px 0 0;
    padding:0 0 10px;
    color:#000;
    font-size:85%;
    line-height:1.5em;
    }

I'm not sure what your original CSS looked like... but with the new changes added, I'm guessing it's something like this. Paste it in and see where we get:

#main {
    width:483px; 
    float:left; 
    background:#fff url("http://www.blogblog.com/rounders/corners_main_bot.gif") no-repeat left bottom;
    margin:15px 0 0;
    padding:0 0 10px;
    color:#000;
    font-size:85%;
    line-height:1.5em;
    }
html>body #main {
    width:485px; 
    float:left; 
    background:#fff url("http://www.blogblog.com/rounders/corners_main_bot.gif") no-repeat left bottom;
    margin:15px 0 0;
    padding:0 0 10px;
    color:#000;
    font-size:85%;
    line-height:1.5em;
    }

Oh, and you put 481px. I changed to 483. Try that.
