By default Joomla’s frontpage is set to 2 column, with one teaser article that is full width.  How can you change it to one column full width all the way down?

This is probably one of the most popular questions I get asked. I admit, It is a bit hard to figure this out without either knowing it already, or Googling it. Let me tell you the secret.

go to your Joomla admin area.  Click menus->main menu->Home

On the right side you will see the parameters for the frontpage module.  Change the columns to 1, from 2 and you are good to go.  Play with the other options as well while you are here.
