CSS DEMOSShape Autorun Slideshow

Date : 17th August 2015

For all modern browsers except IE and Firefox





Information

A simple autorun slideshow using CSS 'shape-outside:polygon' and 'clip-path:polygon' with '@keyframes' animation to produce an overlay to represent a camera diaphragm opening and closing between each image.

This is a responsive slideshow so will resize to fit any browser and device. You will need to refresh the page if you are resizing a PC/Mac browser as the Google Ads are not dynamic and need a page refresh to resize to fit.

Just a pity that Firefox and Explorer/Edge do not yet support these styles.

HTML Code
