[Theme Academica] Footer width 100%

Hello, I’m using Academica Theme from WPZoom;

The content is in a wrap 100px;

For main nav I can expand it to whole width.

But for footer, which is inside the wrap I can not expand it to while window (width 100%).

Is there a possibility for my request ?

And the same question for slideshow (the buid in theme or 3rd party plugins) – I need it to be on whole window – width 100%.

Thank you.
