I’ll be the first to admit I’m not very adept at CSS. So, I’ve changed everything I can think of in the Wordpress theme style.css file in order to change the standard Digg 3 column theme into one that is 1004 px wide and the sidebar and obar turn out correctly. I need the middle of the theme to be 620 px wide and the sidebar and obar to be at least 170 px wide or more.

My test website is breakfasthouse.net and any help will be greatly appreciated.

Have you fixed it in the meantime already? I checked it, and it seems both the selectors .content and .obar have the widths you mentioned.

I've partly fixed it. I'm still not happy with the space between the main inside box and the sidebar and I'd like to push the sidebar over more to the right edge. My goal is to get two photos in the main wordpress theme side by side, one 280 px wide and the other 300 px wide without wrecking the rest of the design. Right now the right photo is 300 px wide and the left photo is 255 px wide which is as wide as I can go before the left photo drops down below the right photo.

Any help will be appreciated.

This theme was based around another Word Press theme, so it is well tested but I am sure that there will be some small changes along the way to make this theme a little better. This is my first free theme, so I have some things to learn I am sure.

Ok, things to change:

Fix the width on the wrapper to:

.wrapper {
float:left;
width:640px;
}

Change the width of the right sidebar column and adjust the margin:

.sidebar, .obar {
float:left;
line-height:12px;
margin:0 15px;
width:150px;
}

Lastly, get rid of that awful table for the images in the center and just float the images, using margin to space them out.

Code:
.sidebar, .obar { float:left; line-height:12px; margin:0 0 0 145px; width:170px; }
I haven't been able to find a way to see the line numbers in WP, so I copy the CSS code into Notepad++ and edit it there, then paste it back into WP.
Be sure to save a cope of the original somewhere first, of course.
