Want to use a single column to display widescreen video thumbnails in project pages

Hi,

Im trying to make a page with video project thumbnails in one column that fills up up the entire width of the web screen. The title of the project would show once hovered over. 

Attached is the cinematography page that I'm trying to apply this format to, how could this be done? Thanks in advance!

Try adding to Design > Custom CSS

.gallery-slideshow {
    max-width: 100% !important;
    padding: 0 !important;
}
