With the help of some members of this community (special thanks to the ever-helpful masterslacker), I was able to customize my LJ and get it looking exactly the way I wanted it. That was a few months ago, and I thought I'd try something new now by adding a header and reducing page width.
All of my customizations were in a theme layer, but a good friend kindly gave me a code for changing the width and adding a header that was supposed to go in the user layer. So without touching the theme layer with the customizations and such, I edited the main/default user layer with stylesheet items.
The header did appear, and the page width changed, but the borders on the userpics (which I had successfully taken away via my own customizations) reappeared, and the titles on the components moved back to be left-aligned instead of centered as I'd wanted. So I was wondering if someone might be able to help me move them to the center again.
Thank you very much! I'd appreciate any help you might be able to give me to that end.
