Header text overlapping header image (fixed)

[cheyinka]

I'm working on a NaNoWriMo 2010 theme for Practicality for my writing journal (the_omelet) and am having difficulties with the header.

If I use
set image_background_header_url = "http://endersgame.net/~cheyan/images/nanowrimo2010_participant_03.png";
set image_background_header_height = 90;
set image_background_header_position = "top right";
set image_background_header_repeat = "no-repeat";
set custom_css = "
h1#title,
h2#subtitle
{
text-align: center;
margin-right: 120px;
}";
then the title and subtitle don't seem to be exactly centered, but if I don't include the margin line, when I make my browser window very small the text goes over the top of the image.

Am I missing something? Is there a better way to get that image up at the top of the page?

Solution: Obviously, if it's going to be centered, the margins on left and right need to be the same. So, I just added a margin-left line to match the margin-right line. :)
