Hi..
You can comment and change some properties in your CSS form like this code
#main_body h1
{
/*background-color:#dedede;*/
margin:0;
min-height:0;
padding:0;
text-decoration:none;
text-indent:-8000px;
/*background-image: url('../../../images/machform.gif'); */
background-repeat: no-repeat;
}
#form_container
{
background:#fff;
/*border:1px solid #ccc;*/
margin:0 auto;
text-align:left;
width:640px;
}
#bottom
{
display:none; /*change to none*/
height:10px;
margin:0 auto;
width:650px;
}
#top
{
display:none; /*change to none*/
height:10px;
margin:10px auto 0;
width:650px;
}
