There’s just about as many ways to implement a slideshow as there as developers — who think their way is best. I recently came across this slick diagonal slideshow by Mary Lou from Codrops. It’s unique in not only that’s it slides diagonally, but also has some really cool UX effects.
When clicking on the current slide, the decorative background element expands to fullscreen, the image moves to the left side of the screen and the content animates in. Animations are powered by TweenMax.
