I'm using the Twenty Twelve theme and have decided to customise it as I cannot find a theme to match my requirements.
I am also going to tackle putting a optin/signup form on top of my banner image but that might be another thread? For now I'd just like to create the columns.
I'm new to coding but learn fast and have already created a child theme with style.css and rtl.css files.
my homepage is http://www.carmsalarms.com
So, is this possible and what is my first step?
