CSS Code:

<style type="text/css">

/* Hide the top bar */
/* copy the styles from viewtopbar.pattern.tmpl */
#patternTopBar,
#patternClearHeaderCenter,
#patternClearHeaderLeft,
#patternClearHeaderRight,
#patternTopBarContentsOuter {
   height:0;
}
#patternTopBar,
#patternTopBarContents {
   display:hidden;
}
/* move the left bar contents down to show the logo */
#patternLeftBarContents {
   margin-top:64px; /* top bar height */
}
#patternLeftBar {
   /* dynamic background image set in topic */
   /* or write a hard coded image location here */
        background-image:url("http://www.cmsaf.mit.edu/twiki/pub/TWiki/TWikiLogos/T-logo-140x40-t.gif");
   background-attachment:relative;
   background-position:1em 11px;
   background-repeat:no-repeat;
   border-top:0px;
}


/* Hide the left bar by default*/
#patternOuter {
   margin-left:0;
}
#patternLeftBar {
   display:none;
}
/* for the content left margin use a bit smaller margin */
#patternMainContents {
   padding-left:2em; /*S6*/
}

</style>
