How do I use the Columns Page Template?

Genesis comes with the ability to create columns (column classes). You can find all the code available for this feature right here.

You will need to login to the Studiopress website in order to access this page. You should have a login for their site if you have personally purchased the Genesis framework from them. If you obtained Genesis through another method, you will need to purchase your own copy in order to access this content.

An alternative solution would be to use this plugin.
