Fix · Pages, phones and Arabic

Sticky header or sidebar does not stick

What you may see

position: sticky does nothing

Most likely cause

Sticky needs a "top" value and no parent with overflow hidden/auto/scroll that cuts it off, and a parent taller than the sticky element.

Check first (about two minutes)

Does the element have top: 0 (or another top value)?
Do any parents have overflow set?

Prompt language

You are a senior front-end engineer who knows HTML, CSS, React, phones and Arabic right-to-left pages, and explains things 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.

Sticky header or sidebar does not stick

WHAT I DID BEFORE IT HAPPENED
[write in a few words what you did before it happened]

MOST LIKELY CAUSE
Sticky needs a "top" value and no parent with overflow hidden/auto/scroll that cuts it off, and a parent taller than the sticky element.

DO THESE STEPS, IN THIS ORDER
1. Check the element for top, and its parents up to the body for overflow, height and display settings.
2. Fix the one parent that breaks it, or move the sticky element out of that parent.
3. Check it on a phone, including under the browser bar.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- The element stays at the top while scrolling on desktop and phone.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not turn it into position: fixed unless you also fix the space it leaves.
- 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.
