Remove padding from textwidget

Changing padding: 0 in your CSS should push the slider out to the borders of your body:

.banner .textwidget {
    background: none repeat scroll 0 0 #fff;
    line-height: 1.625;
    padding: 0;
}

it’s not working ??

sorry got it working now!

I’m glad. I was going to add that sometimes you need to add !important after the CSS.

padding: 0 !important;

.banner .textwidget {
padding: 0;
}
