Expand Slider Full Width

I need a way to force the slider to expand to full width.

I need to be able to use different captions on all slides and hence the background image slider does not work.

But the regular slider element does not go the full width which is all I need.

Technically this is the CSS I would want to apply but it is not applying:

.upfront-region-container-sliderb .upfront-grid-layout {
width: 100% !important;
}
.upfront-region-container-sliderb .upfront-output-uslider {
padding: 0px !important;
}
