If you do that, the banner goes away
Oh BTW, for more clearity, this is the code I used in stylename_cs.css to get the banner working.
/* header logo */
.pun H1
{
/* your logo and position */
background-image: url(../../img/logo1.png);
background-repeat: no-repeat;
background-position: left; /* you set your logo position here */
display: block;
height: 70px; /* logo height in here add width: size px if u need*/
}
/*header title*/
.pun H1 span
{
/* your font style */
color: #0066B9;
font-size: 20px; /* title size */
font-family: Tahoma, Verdana, Arial, Helvetica, sans-serif;
text-transform: none ; /* transform text: uppercase, capitalise */
text-decoration: underline; /* decoration: none, overline */
/* position for your text (board title) with the logo */
position: absolute;
top: 40px;
left: 90px;
}
