How do I implement border light surround animation in CSS?

Use conic-gradient on an oversized ::before, spin with keyframes, clip via overflow: hidden. HagiCode's code above is production-ready—copy, tweak colors.

Does border light animation work on mobile?

Yes, but throttle animation duration to 4-5s on prefers-reduced-motion. Test GPU load; box-shadow alternatives shine for perf.

What's the best alternative to full border glow?

Side-breathing shadows for lists. Lighter, accessible, still grabs eyes without full spin.
