I am a WordPress newbie, I started using it 2 months ago, and that too on genesis framework's News theme. Right now, am able to do nearly all modifications that's been needed by my bosses in the site including adding widgets, plugins and customizing the site.
But I feel as am still not known with the core of theme, how it works, how its made. How to add code snippets, apart from editing it from admin etc.
So if you can suggest me some book or literature which can instruct me from basic to advance topics of theme and WordPress.
I have been through codex and nettus vids. :(
