Im currently using this theme

Basically i need to be able to change the QVC code and the description, right now im using “WP POST STYLE” plugin which lets u make custom css classes, this allows me to have this for my css.

<style type="text/css">
#wrapper {
	height: 225px;
	width: 550px;
	margin-top: 0px;
	margin-right: auto;
	margin-left: auto;
}
#banner {
	height: 100px;
	width: 550px;
}
#qvcCode {
	height: 125px;
	width: 125px;
	left: auto;
	float: left;
}
#textArea {
	width: 425px;
	padding-left: 125px;
	height: 125px;
}
</style>

And then in my post i can go to the html edit mode and put this in.

<div id="wrapper">
  <div id="banner">banner</div>
  <div id="qvcCode">qvcCode</div>
  <div id="textArea">textArea</div>
</div>

So i can get it to work like this but id rater be able to not have to copy the div tags into the html of the post every time i want to use it, sorry if this is confusing but i need help really bad!

aslo im looking for people to help with the site i cant offer pay at this time but i may be able to in the future, thanks.
