I'm using the Twenty Eleven theme on my new blog Math ∩ Programming, and I'd like to have the h1 and h2 headers be larger, and different. I can't even tell the difference between bold text and an h2, which makes navigating for information harder on my (future) readers. This needs to be changed in the default theme, unless there is an easy (non-repetetive) way to fix this.
The blog I need help with is jeremykun.wordpress.com.
