I am trying to customize my blog. I like the ones where you can do a custom background and a custom header, and I'm really grateful that WP has been adding more of those. However: every time I add a custom background (have tried it with Modularity Lite, Koi, & Wu Wei most recently but a few others) the table with my main text goes transparent. I don't want this! I want my tables to be normal & my background to just be on the edges. Is there ANY theme that will do this, or any way to correct it from being transparent on the mentioned themes?
The only one I've found that *kinda* works is the them "Bueno." But, the problem with it is that it has a header that won't go away or be customized. It automatically puts my blog title & menu in black text, which doesn't work with the black background I want to use. When I go to "Header" options, I can upload my own header but it just goes under the one automatically put in instead of replacing it. If anyone knows a way to make the automatic disappear or even just change the color font, I would be really grateful.
The blog I need help with is brittanyib.wordpress.com.
