You might have to manually modify the codes if the theme doesn’t allow.
Here’s what I copied:
<div class="header-desc fright"><p><img src="/wp-content/uploads/2011/10/EXPlogoLong1.png"></p></div>
CSS:
.fright {
float: right;
}
style.css:74
.header-desc {
width: 468px;
margin: 25px 20px 10px 0;
min-height: 60px;
}
I’ll leave the rest for you to explore. ??
