Thesis Feature Box and HTML | Bloggers Lair | Yakezie Forums

Hey there gang, I'm working on my next goal for my site and need some advice. I don't know code very well and do not have a budget to hire someone to do this work for me (plus, I like learning new things, it can only help right  ). I am using Thesis Wordpress Theme and I aim to use the Feature Box. What I need to know is:

-Where can I learn basic HTML? (is there a good tutorial site for this?) 

     - I want to incorporate a background image and insert text and other things within the background. I know basic html such as (a href and img src) but those are all I know. 

-Also, I would like to know how to edit the "tabs" at the top of my page. I want to change the look of them, not the text within. 

Thanks Mike, I will check it out
