What I did here is use my own image for the page background so that I can have my organization's header as the header for the page (above the image header of the Twenty Eleven theme). Through my basic CSS customization I've achieved the look that I want.
With one exception... The page background image that I am using is static and doesn't resize automatically to fit the width of the window like the header image does.
I've tried a bunch different CSS code to accomplish this and this is what I'm using at the moment (to no avail):
#page {<br />
background:url('http://beaconofhopeblog.files.wordpress.com/2012/10/blog-banner.png') no-repeat, #FFFFFF;<br />
width:auto;<br />
}
Some stuff I've read is telling me that this kind of customization would only be possible if I self-hosted the blog.. SAY IT AIN'T SO! I'm new to all of this and wouldn't want the extra responsibility (and headache) of self-hosting when all I want is such a simple tweak.
Any help is MUCH appreciated!
The blog I need help with is blog.beaconofhope.org.
