How to make a larger frame text box

I want to make a new page and see a large colored (or with background picture) frame, which I will insert text inside. It seems whenever I make a new page (with ‘full width’ definition in the dashboard) there’s always a frame which doesn’t let me to spread it from side to side.
I hope my explanation is clear…

Hello there,

Have you tried the “Front Page” template? Doesn’t it work for you?


I’m using LiveComposer. See here:

the box is streched from right to left in the middle of the page.
