I wanted a different blockquote in this theme so I modified it in style.php

 

from :

blockquote {
font: italic 15px/130% “Times New Roman”, Times, serif;
padding: 8px 30px 15px;
}

to :

 blockquote {
clear:both;
display:block;
overflow:auto;
background:#ebf3fc url(images/blockquote.png) repeat;
border:1px solid #ccc;
border-radius:5px;
margin:1em 40px;
padding:4px 10px;
width:auto;
color:#666;
text-shadow: 1px 1px 0 #fff;
}
