This is a repository that is accompanied by an artilce series on my code site at desginkojo.com Part 1 of the series can be found at https://designkojo.com/image-reveal-hide-viewer
Most recent branch is https://github.com/siramsay/image-hide-reveal/tree/make-responsive and the artcile for it can be read here https://designkojo.com/slide-and-hide-show-part-2b
The article series is a much about showing development is a irritative process as it about the viewer. It is also about how you can use Git to manage branches of projects and also a place for be to practice technical writing and content creation. It is hoped however, that a final library can be created that will be useful for others in the future.
