I'm sure I'm missing something here.

I have Artisteer and used it to make a custom template for Blogger / Blogspot. According to both (Artisteer and Blogger) it should work - but it's not.

After I upload the template (directly from Artisteer) it looks like the width is messed up.

The header - it looks like the image / background (even a plain color) looks like it is too small so it is centered and at the top - leaving white areas around it. The image has the color to the right of it a little, too, but then is white.

Same with the background if I have a texture. The main body doesn't have the background color and the side bar has the same issue - background color behind most of it with white to the right.

Should I just "customize" the template though Blogger's control panel?
