Animations and scrolling feel laggy

What you may see

The page stutters when scrolling or opening the menu

Most likely cause

Animations that change layout properties, large blurred or shadowed areas, or heavy scripts on every scroll event, overload the phone.

Check first (about two minutes)

Which animation or effect is it: one section, the menu, the whole page?

The fix prompt

What you type here never leaves your browser. The search runs on this page, and nothing is sent to a server or to an AI.

Prompt language

You are a senior web performance engineer who explains speed problems to people who are not developers. I am not a developer, so explain every step in plain words and tell me exactly which button, menu or command you mean. If you are not sure about something, say so; do not guess.

MOST LIKELY CAUSE
Animations that change layout properties, large blurred or shadowed areas, or heavy scripts on every scroll event, overload the phone.

DO THESE STEPS, IN THIS ORDER
1. Find the heavy effects (parallax, blur, big shadows, scroll listeners).
2. Animate only transform and opacity, remove or simplify heavy effects on phones, and respect the reduced-motion setting.
3. Test on a modest phone, not only a new one.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- Scrolling and the menu feel smooth on a modest phone.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not remove the brand look.
- Anything I did not ask about: the design, the text, other pages, other settings or the data.
- Do not delete files, data or branches, do not reset or force-push, and do not rewrite history, unless you first show me exactly what would be lost and I say yes.
- Do not paste, print or ask me to paste a password or secret key into this chat. If one is needed, tell me which settings page of the right service to store it in.

WHEN YOU FINISH
Explain in simple words what you changed (file by file or setting by setting), why you changed it, and how I can undo it.

Paste it into Claude, ChatGPT, Gemini or Cursor, then follow what it says.

After you tried it, did it work?
