Moderately Heavy CSS Animations + Large Content

This mini site is designed to demonstrate that even “normal-looking” UI effects—animated gradients, blurred layers, box-shadows, and many subtle floating elements—can reduce responsiveness on low-end devices. Use it to show scroll stutter, delayed taps, and sluggish page navigation.

Try this: open Articles, scroll quickly for 10–20 seconds, then switch to Dashboard and back. On low-end phones you should notice occasional dropped frames and a “heavy” feel.

Common Effects

Mild blur, translucent headers, shadows, and multiple animated surfaces are common in modern UI.

Continuous Motion

Continuous animations keep the renderer busy, especially when combined with large content.

Navigation Feels Slower

Switching pages can feel delayed because styles, paint, and compositing work stacks up.

Scroll Stress Test

The Articles page contains lots of text, repeated cards, and sticky UI to stress scrolling.
