The creator of this animation was inspired by his trip to Tunisia where he wandered around following a stranger who insisted on showing him something.

The animation resembles a number of random forcefields that move in a labyrinth-resembling manner and never hit one another. After a certain number of steps, a spot becomes free.

Pure CSS Background Image Scroll Effect

Created by carpe numidium

This background only animates when you scroll. In the code, attach the fixed background image to the HTML. Assign an additional red color gradient with transparency and mixed-blend-mode to the body. The mixed-blend-mode property is responsible for determining how an element’s content will blend with the content of the element’s parent and background (MDN).

CSS Multiple Background Image Parallax Animation
