Remove FOUC on Lightslider jQuery Carousel

When more than one slide is used on a lightslider slider/carousel, the slide images are initially loaded underneath each other and jump into place which causes the layout to jump around which is known as a flash of unstyled content or FOUC.

There is a CSS class name that already ships with the lightslider CSS ‘cS-hidden’

.cS-hidden { height: 1px;
