Is sonicworld.net your site or the site whose sidebar you’re trying to mimic?
If it’s not your site can we have link to your style.css or site in order to give you specific code?
To answer you height question you would add the property like this:
#sidebarleft h2 {
font-family: Arial, sans-serif;
color: #E8CFA9;
padding: 2px 8px 2px 8px;
margin-top:8px;
background:#480000 url(img/h2l.png) top right no-repeat;
border-bottom:1px solid #E8CFA9;
height:30px;
width:150px;
}
This assumes your sidebar is in a element with the id of “sidebarleft”
I got that id from the sonicworld css, so, if thats not your site your sidebar id maybe different.
