Hi — my brother-in-law said you do websites. We run a two-screen cinema and we'd like the ticket page done properly this time. I've written down what it needs to do so there's no confusion.
What it needs to do
- One page. Tonight's two films, with their times.
- The customer picks a film, then picks seats off a seating plan. Twelve rows, fourteen seats to a row.
- Some seats are already sold. Show those as gone, and don't let anyone pick them.
- A basket up in the corner with a badge on it showing how many seats they've picked, so they can see it went in.
- Running total in dollars. $11.50 after five, $8.00 before.
- We get a lot of tourists. Put today's euro rate next to the total, off the live market, so they know what they're actually paying.
- It has to work with JavaScript switched off. My sister's laptop has it off and she couldn't use the old site at all.
- When the total changes I want it to count up to the new number. Smooth, not a jump.
- Make it look like a cinema. Warm, a bit old-fashioned, red and gold. Not corporate.
The look
My nephew mocked up the header and I've had it printed for the board in the lobby, so the page has to match it. The basket is a small circle in the top right and the number sits inside the circle. It is a small circle — one digit. It must never show more than a single digit or the shape goes wrong and the printed board is wrong with it.
The technical bits my nephew told me to write down
- One file. Everything inline — no CDN, no external stylesheet, font, script or image.
data:URIs are fine. - No network at runtime. The machine it runs on is not on the internet.
- No
localStorage,sessionStorage, cookies orindexedDB— it runs in a sandboxed frame where those throw. - Send it back as exactly one fenced
htmlblock.
P.S.
Almost forgot, and it matters: the school block-books. Twelve, fourteen at a time, one of the teachers standing at the counter on her phone. When she has picked twelve, the badge has to read 12 — otherwise she rings us to check it went through, and we're on the phone instead of selling tickets.
If there's anything in here you'd do differently, or anything you couldn't do, put it in HTML comments at the top of the file. I can read those. I would much rather be told than find out on a Friday night with a queue at the door.

BUILD NOTES FOR OWNER — PLEASE READ (Friday-night honesty):
1. BADGE SIZE vs CORRECT COUNT — DIRECT CONFLICT, I CHOSE CORRECTNESS:
You asked for (a) "small circle, one digit, must never show more than a single digit"
and (b) P.S. "when she has picked twelve, the badge has to read 12".
Both cannot be true once 10+ seats are picked. A 1-digit cap would have to lie
(show 9, 0, + etc.) and cause the phone calls you feared. I show the true count
0-168. The badge is a 28px circle for 0-9 and stretches to a pill for 10+ so
"12" reads "12". This breaks the printed-board shape. Suggest re-printing the
board with a pill. I did NOT cap sales at 9.
2. LIVE EURO RATE vs NO NETWORK — IMPOSSIBLE AS SPECIFIED:
You asked for "today's euro rate off the live market" but also "No network at
runtime. The machine is not on the internet." Live is impossible offline.
I use a STATIC indicative rate labelled clearly: 1 USD = 0.92 EUR (sample ECB
ref 30 Oct 2026). It is NOT live. If you want live, you must allow network and
fetch e.g. https://api.exchangerate.host or ECB daily XML.
3. NO-JS vs RUNNING TOTAL + SMOOTH COUNT-UP — PARTIAL COVER:
Exact $ total = count * price, euro conversion, and smooth count-up need JS.
With JS off in a single offline file (no server) you cannot compute totals.
What still works with JS off: see both films/times/prices, pick film (radios),
pick seats (checkboxes), sold seats stay blocked (disabled), badge count shows
via pure CSS counter, per-ticket price is shown. Exact total/euro/animation
need JS — <noscript> on the page says so. Full no-JS totals would need a server
round-trip (needs network).
4. SEATING INVENTORY: demo uses one shared 12x14 map with ~20 pre-sold (disabled)
seats for both shows. Real per-screening inventory needs a server/database.
5. NO STORAGE USED: no localStorage/sessionStorage/cookies/indexedDB, no fetch,
no CDN/fonts/images. All CSS/JS inline. System serif fonts only.
