Here is the 19 simple, beginner level hover animation using CSS. The logic behind the examples are briefly explained as comments in the CSS code section. The before and after pseudo elements are used with simple CSS transform property, JavaScript is not used in these examples. Hope you will like it, happy coding.

Great collection. The ::before/::after approach for hover effects is underrated — it means the hover state is defined entirely in CSS without touching the element's own layout, which makes it much easier to add to existing components without side effects.
One thing I've found useful when working with hover animations in product/brand contexts specifically: combining CSS transforms with filter properties creates really polished UI transitions that also happen to be GPU-accelerated.
The classic example is a grayscale logo grid — logos start desaturated (filter: grayscale(1) + low opacity) and reveal in full color on hover. The implementation is just two CSS properties with a transition, no JavaScript at all:
filter and opacity both run on the compositor thread, so this stays smooth even on slower devices. I use this exact pattern in a Shopify app (Eye Catching on the Shopify App Store) for partner/brand logo sections — it's one of those cases where the CSS-only approach is actually better than a JS animation because there's nothing to debounce or cancel on rapid mouse movement.
