I am trying to customize the header for the Imbalance 2 theme. I want my header to be a banner that spans the length of the page, rather than a 200px square on one side. A perfect example of what I want is: http://thepatternedplate.wordpress.com/ Where in the coding do I change this?? what coding do I use?? any help would be greatly appreciated.
The blog I need help with is mariellejanedavis.wordpress.com.
