Forum:Extending background width for main page testing?

My question is short and simple. Is it possible to extend the width of a page to full resolution, like the main page? I clearly know it is currently not an option on Wikia, but let's say I'm trying to design a new main page? Doing it in a sandbox would shrink it all to 75%. Toying with it on Main Page is something nobody would love to endure watching as their browse. My only current solution is submitting and comparing edits as it's the only section on Wikia that does not have that sidebar, but it's forcing me to publish too much.-- Zikkun (talk)  01:07, June 18, 2012 (UTC)
