Creatively Beautiful CSS Background Effects
Good web design leaves a lasting impression on visitors, and there’s always something extra enchanting about a well-made animation. Whether you go all out with an animated starry or gradient background, or you just add some elegant and subtle parallax effects to your site, it can do wonders for your design.
CodePen hosts exclusively open source code, made by developers as a contribution to the community. So, if one of these effects caught your eye, feel free to copy it, tweak it, or use it as a base for making your own CSS animations.
Just remember to use the same license, and everything on CodePen is free to use.
