If you look at my blog, katyloves.com, there seems to be an inch of white on the left of the page. I've tried removing the padding, but that doesn't work. I'd like for their to be no white on either side, so more of my page fits in the actual window. If that makes sense. Thanks!

remove the '.coltwo { width: 800px; }' you have in the CSS Inserts

I did that and there's still a white space to the left. It just ended up pushing my right sidebar into my post.

that white space is the page background. Add this to your CSS Inserts, the red is the body of the page, the blue is the page container
Oh and fix your CSS you are missing a closing '}'

body {border: solid 1px red;}
#wrapper {border: solid 1px blue;}

I added it and also added the missing } not sure where to go from here. I can see the blue and the red now.

the blue area is the layout width (ato->Style & configure LAYOUT-> Layout WIDTH and type (FLUID or FIXED) ) which will hold your contents - outside that is just background

is that outside area the 'white space you are talking about?

The part past the blue is what I want to get rid of. I've seen blogs that have no background space to the right or left.

You can do that but you have to have a variable width site - go to ato->Style & configure LAYOUT-> Layout WIDTH and type (FLUID or FIXED) and read about the settings

Perfect, thank you so much!
