I could not find how to make a single text block with a background such as here: http://dev.sacrealtor.org/index.php/home/home-two 

Do I need to edit the css in the backend to achieve this? 

I also could not figure out how to delete a text layer once I've added it. 

Update: I have discovered how to delete a text block. Now I have no idea how to add a button without adding it in the text block. Is there better documentation that I'm missing? Pls halp.
