This lightweight slideshow was found at https://codepen.io/leemark/pen/DvliI. It can be quickly set up, and more (or less) images can be added. A couple of tweaks you need to know about:
The container 'x-fade' is a list container with relative positioning, and the list items are positioned absolute. This leads to so-called 'parent collapse' and any new content placed below this will slide up behind the images, unless you give the list container (the parent) some dimensions, preferrably the same width and height as the images. The container 'banner-holder' also needs those same dimensions.
In order to keep these hints and tweaks I recommend saving this as a theme. A component of the slideshow can be made by selecting the container 'x-fade'. If you want the text overlay too, then make the component by selecting the container 'banner-holder'.
