Today I played around a little with CSS variables and wrote a small web page that makes use of these variables. The website is a picture gallery. When users click on the image, the previous image moves from the display and the new window appears. Click right and the gallery moves to the left, click right and the gallery moves to the right. To make the transition not too boring, I used Cubier-Bezier transformations. You can find the website here and the code here.
