Thematic Sidebar Width

First off, my blog is located at https://www.thehipsoiree.com. Second, I’m a complete css newbie. Obviously.

NOW, back to the topic. My blog was created with Thematic. I want to change the width of the sidebars (preferably the right, but I’ll take either at this point) to accomodate 250px jpgs. Here’s my current code:

#main {
    width: 1100px;
margin: 0 auto;
overflow: hidden;
position: relative;
background: white;
margin-top: -45px;
}
#container {
    width:1100px;
    float:left;
    margin:0 0 0 10px;
}
#content {
    	margin: 0 240px;
    overflow:hidden;
}
#primary {
    width:220px;
    float:left;
	margin: 0 0 0 -1110px;
}
* html #primary {
	left: 20px;
	position: relative;
}
#secondary {
    width:210px;
    float:left;
	margin: 0 0 0 -230px;
}

I’m assuming it just takes some messing with the width numbers, but I’ve tried several different variations and haven’t had any success.

At this point I’m going to straight up beg for your help. Please, please, please!!!!
