.banner&.banner--optimizedlatter is used for mobile optimized images that have a different aspect ratio than the desktop images - Slideshow & slide reserved for the future in case the banner will be configured to a slideshow

.banner__containercolumn that houses content. There can be at most 2.banner__containers in the.banner..banner__contaners remain side by side on regular.banner, on.banner--optimizedthey stack, the second/right column goes on top and the left on the bottom.
