Articles: Scroll Performance Demonstration

This page intentionally combines common UI effects: sticky navigation, soft blur on the header, decorative glow overlays, shadows, and repeated content cards. This version removes all CSS animations so you can compare responsiveness on low-end devices.

What to do: scroll continuously for ~15 seconds, then quickly tap “Dashboard” and return to “Articles”. Compare how “connected” scrolling feels vs the animated version.

sticky header blur + transparency shadows many cards no motion

Section 1 — Everyday Motion (Removed)

Many modern UIs rely on gentle motion to feel “alive”. In the animated variant, cards fade in and background elements drift slightly. Here, everything is static to provide a baseline.

On low-end hardware, removing continuous motion often improves scroll consistency and tap response.

This page keeps the same amount of content so you can test “long reading” conditions without animation.

Section 2 — Shadows, Transparency, and Composition

Shadows and translucent layers increase visual depth. Even without animations, these styles still add some cost—just typically much less than when combined with continuous motion.

Scroll fast and stop suddenly. This version should settle more consistently than the animated version.

Then tap a navigation link immediately after stopping.

Section 3 — Repetition Magnifies Cost

Repeated cards create repeated paint work. In the animated version, those cards also animate, which can increase main-thread pressure on weaker devices.

This section remains to keep the scroll long and realistic.

Compare how stable scroll feels over time between variants.

Section 4 — Long Reading Experience

Long-form pages often include cards, callouts, and fancy headers. The page gets heavier as more components appear in the viewport.

With no animation, the browser has less ongoing work while you scroll.

Keep scrolling to create sustained load.

Section 5 — Navigation Under Load

Navigation can feel worse when the device is already busy. In the animated variant, continuous motion keeps the renderer active, which can amplify delays.

Here, you should see more consistent taps when switching pages.

Try tapping Dashboard while scroll momentum is still active.

Section 6 — More Content, Same Effects

This section exists mostly to keep the viewport full of layered content. The more you scroll, the more obvious performance differences become.

If you want a stronger comparison, run the animated version for a minute, then switch back here.

On low-end devices, continuous animations can also increase heat and reduce smoothness over time.

Section 7 — Realistic UI “Jank” (Reduced)

The goal is to show mild, realistic jank. With animations removed, you should see fewer frame drops and less input delay, especially on weaker phones.

Watch for more even scroll velocity and quicker tap response.

On better devices, both versions may feel fine—contrast matters most on low-end.

Section 8 — End of the Page

If this version feels noticeably smoother, you’ve demonstrated the impact of continuous CSS animations on low-end hardware.

Now switch to the dashboard and scroll the long list.

Repeat a couple times and compare devices.
