Reply To: Home Slider Wide Widget – Background Fixed Postion

The slider-wide section is set to 100% width, so you could change that part to a fixed size like this –

.slider-wide {
    clear: both;
    margin: auto;
    width: 1140px;
}

But you’ll probably want something behind that as it will show up in the middle and leave white empty space on the sides depending on which size browser you’re viewing from.
