# Conference > A five-page conference website template for tech summits, webinar series, festivals with a livestream, church services and esports events. A live stage feed stays on screen for the whole visit and keeps playing while the pages change around it; the programme runs as a three-hall guide with a personal day planner.

This five-page template puts one live picture at the centre of both. The home page sets a poster headline fitted flush to the full width of the screen with the main stage's feed cut into its first line, and under it a strip shows what is on in each hall right now and what comes next. Open Circuit, a fictional civic tech summit in a converted Leeds tram depot, is the worked example; the same pages suit a tech or business conference, an online summit or webinar series, a church with live services, an esports tournament or a festival with a stream. The feed never stops. It sits in a slot on the page, docks to a corner when the slot scrolls away and comes back when it returns. Page changes move the page and leave the picture: the page eases out to the left, the stream holds on screen and then flies to its place on the next page as that page comes in from the right, Back the other way, without a restart. A hall switch on the feed changes the picture and repaints the site's "now" colour; halls without a stream say so and show their next session instead. The programme is a broadcast-style guide with time running across three hall lanes. Tap or drag sessions into My Day to see clashes and walking time between halls, and the passes page builds an order from those picks with a ten-minute pass hold that survives every page change. An ink-dark stage, warm paper sections between the dark ones and three hall colours carry the whole system; change the hall names, colours, photographs and copy to make it yours. Everything is static HTML, CSS and JavaScript with bundled images and video and no build step. ## Features - Five standalone HTML pages: home, programme, speakers, venue and passes - A persistent live feed outside the page: it sits in each page's slot, docks to a corner (or the phone bar) when the slot scrolls away, and can be paused or minimised - Page changes that move the page and leave the picture: the stream holds on screen while the next page loads, then flies to its slot or dock on the new page; Back runs the other way - Hall switch on the feed: Hall A plays the live loop, Halls B and C show a photograph with an honest "not live" label and their next session - Poster masthead with both lines fitted flush to the measure, refitted automatically if the words change - Real-time day strip with a now-line and rolling now/next labels for each hall - Programme guide with time across three hall lanes, track and day filters, deep links such as ?track=data&day=fri and a full session listing with calendar files - My Day planner on every page: tap or drag sessions in, see clashes and walking time between halls, kept in the browser - A live "on now" list of all three halls in the Speakers and Passes page heads, each row linking to its session - Speakers page with a Flip regrid by track, monochrome portraits that return to colour on hover, a profile drawer and a typographic index of 48 more names - Venue page with the stream playing on the stage photograph's own screen, a drawn floor plan with a scroll-drawn step-free route, and a real walking map from the station - Passes page with a ten-minute pass hold, a header timer that survives navigation, and an order built from My Day; a front-end demo checkout - Real links and complete pages without JavaScript; instant page swaps and a paused stream under reduced motion - Bundled, graded WebP photographs and two H.264 stream loops, with credits ## Use Cases - Tech, business and public sector conferences with several stages or rooms - Online summits and webinar series built around a live stream - Churches and ministries streaming services to a wider congregation - Esports tournaments, film and music festivals with live coverage of one stage ## Questions about this template ### Which kinds of event can use this template besides a conference? Any event with rooms and a stream. An online summit or webinar series keeps the feed and programme as they are; a church can treat halls as services or sites; an esports tournament or festival can make the halls stages or courts. Swap the hall names, sessions, photographs and stream loop, and the guide, My Day and transition carry over unchanged. ### How do I put my own live stream in the feed? The feed is an ordinary HTML video element with a looping file, so replace the two MP4 files with your own loop of the same proportions. For a genuinely live stream, point the video at your provider's HLS address with their player library, or swap the video for their embed inside the same feed element; the docking and transition keep working because they move the container, not the video. ### How do I change the programme, halls and tracks? Edit the session listing in programme.html: each session is one list item with its day, hall, start, end and track as data attributes. The guide, the home now/next strip, the feed's next-session labels and My Day all read that one list. Hall names, walking times between halls and pass prices are short settings at the top of the script. ### Does the pass checkout take real payments or save bookings? No. The passes page is an unwired static front end. It holds a chosen pass for ten minutes in the visitor's browser tab, builds an order from their My Day picks and shows a demo message on checkout; nothing is charged, reserved or sent. Connect your ticketing provider, such as Tito, Eventbrite or your own checkout, and update the visible notes before selling passes. ### Is the newsletter sign-up connected to anything? No. The footer form is a front end only: it checks that an email address was entered and shows a confirmation, but sends nothing. Point it at your mailing tool, for example Buttondown, Mailchimp, Formspree or your CRM, and remove the demo note in the footer of each page. ### Are the speakers, sessions and venue real? No. Open Circuit, its 72 speakers, organisations, sessions, figures and the depot are fictional examples. The portraits and hall photographs are licensed stock of unrelated people and places, the depot exterior is an AI-generated concept image, and the stream loop is licensed stock footage. Replace them with your own speakers, programme and photographs, with permission, before you publish. ## Vibe-Code Ready Setup This template includes `START-HERE-AI.md`, a product-specific copy-paste setup prompt for Claude Code, Cursor, GitHub Copilot, Windsurf, Gemini, and other coding assistants that can edit files. It tells the assistant to rebrand the template in place for your business, keep the design and animation, replace the fictional example across every page, and report which photographs to replace, which details it invented, and what it tested. [How AI-assisted setup works](https://gsapvault.com/vibe-coding) ## How It Works ### One picture for the whole visit The live feed lives outside the page content, so it keeps playing through every page change. Each page marks where it wants the picture with a data-screen slot: in the home masthead, in the active hall's lane on the programme, on the stage photograph's screen at the venue. Pages without a slot, or a slot scrolled out of view, dock the picture to the corner or the phone bar. ### Pages change, the picture stays Internal links fetch the next page while the current one slides a few pixels left and fades. The feed does not leave with it: it holds in place and keeps playing, so a slow connection shows the stream and never an empty screen. When the new page comes in from the right, the feed flies to its place there, the page's slot or the header dock. Back runs the other way. The video element is never replaced, so the stream never restarts. ### Halls, the clock and now A demo clock runs through the event day in real time, so the home strip always has a session on now and one next in each hall. The A, B and C switch on the feed changes the picture with a hard cut and repaints every now-line and current-page marker in that hall's colour. Hall B and C have no stream, so the feed shows their photograph, says not live and gives the next session time. ### Planning a day Programme cards are buttons: tap one to add it to My Day, or drag it onto the list beside the guide on a desktop. Clashing picks shake and are flagged, and the list shows walking time between halls and warns when a change is tight. The passes page suggests the cheapest pass that covers the picks and holds it for ten minutes; the checkout is a front end only. ### Calm when it needs to be Reduced motion swaps pages instantly, re-seats the picture without a tween and pauses the stream behind a play button. Without JavaScript every link loads its page normally, the home slot plays the stream directly, the programme is a dated listing with calendar files and every speaker's profile is printed under their photograph. ## Documentation How this template works and how it goes into a page. The reference you use once you own the files (worked examples, events, the programmatic API, the class list) ships with the download. ### Quick Start Upload the folder to any static host and open `index.html`. Keep the five HTML files beside `assets/` so relative links keep working. There is no build step, framework or package to install. Serve the files over HTTP or HTTPS to see the page transitions and the live now/next labels. While editing, use any local static server (for example `python3 -m http.server` in the folder) and open `http://localhost:8000/index.html`. Opened straight from disk the pages still work, but links load normally without the transition and the clock-driven labels keep their written text. GSAP, ScrollTrigger and Flip load from a CDN; MapLibre loads on the venue page only, when the map nears the screen. Fonts, images, video, styles and scripts are bundled locally. ### Using It With Your Own Design 1. **Identity.** Replace "Open Circuit", the dates, the address and the fictional-event note in the header and footer of each page. They are repeated in all five files so each page stands alone. 2. **Halls.** Rename the three halls in the markup (the feed's A/B/C switch, the home strip, the venue plan, the hall cards) and in the `HALLS` setting at the top of `assets/script.js`. `STREAMED` says which halls have a stream; `WALK` holds the walking minutes between them. 3. **Programme.** Edit the session listing in `programme.html` (see Programme and My Day). Everything clock-driven reads it. 4. **Stream and photographs.** Swap the files in `assets/media/` and `assets/img/` keeping the names and proportions, then update alt text and captions to describe what yours show. 5. **Colour and type.** Edit the tokens at the top of `assets/style.css` (see Palette and Fonts). 6. **Passes and sign-up.** Connect the passes page and the footer form to real services before selling anything (see Passes). Everything visual lives in `assets/style.css`; everything interactive lives in `assets/script.js`, one function per feature, each returning early when its markup is absent. `assets/page-router.js` is the small router underneath the transition (link handling, fetching, history, scroll and focus); you should not need to edit it. Delete a section from the HTML and the rest keeps working. ### Pages and Configuration | File | Content | | --- | --- | | `index.html` | Fitted masthead with the feed cut into it, the now/next day strip, figures, four track rows (a photograph appears on hover), six speakers, the depot and its three halls, pass prices | | `programme.html` | Day and track filters, the three-lane guide with My Day beside it, then every session as a dated listing with calendar files | | `speakers.html` | Track filter beside a live "on now" list, 24 photographed speakers with a profile drawer, 48 more as a typographic index, call for speakers | | `venue.html` | Hall A stage photograph with the feed on its screen, floor plan with the step-free route, walking map from the station, access, hotels | | `passes.html` | A live "on now" list in the head, three passes with a ten-minute hold, the order built from My Day, questions | Hooks you will meet in the markup: - `data-page` wraps each page's content and footer. Everything outside it (the header, the feed, the phone bar and the two sheets) persists across page changes and is repeated in every file. - `data-screen` marks where a page wants the live picture. Use one per page; a page without one docks the feed. `data-screen-hero` on it (or its parent) means the transition waits for that slot's image before landing. - `data-rig` is the feed itself. `data-rig-video` is the stream, `data-rig-still="b"` a hall's still photograph, `data-hall="a"` the switch buttons. - `data-session` on each programme listing item with `data-day`, `data-hall`, `data-start`, `data-end` and `data-track`. - `data-pick="session-id"` on any button makes it add or remove that session from My Day; `data-myday-list` renders the list; `data-myday-count` shows the count. - `data-hold-time`, `data-hold-chip` and `data-pass-hold="day"` drive the pass hold timer. - `data-fit="one"` / `data-fit="two"` are the masthead lines; `data-rise` lifts them in on first load. - `data-reveal-group` and `data-hero-fade` give a gentle rise on scroll and on load. ### The Feed The feed (`.rig`) is a single element outside the page content, so it never reloads. It has four modes: - **slot**: positioned over the page's `data-screen` slot. It is placed in document coordinates, so it scrolls with the page natively and never trails behind it. - **dock**: an 80 by 45 pixel thumbnail in the header beside My Day on desktops (64 by 36 between 768 and 1023 pixels wide; `data-bar-dock`), or a 96 by 54 thumbnail at the left of the phone bar (`data-phone-dock`). It docks when less than half of the slot is on screen and flies back when it returns. Both docks are empty places that open only while the feed sits in them (`html[data-dock-open]`), so the picture is never shown twice and never floats over the page. On a desktop, clicking the header thumbnail (`data-rig-expand`) opens a larger 280 by 158 picture at the bottom right with hall, pause and back-to-page controls; its arrow button (`data-rig-collapse`) puts it back in the header. On a phone, tapping the bar thumbnail scrolls back to the page's picture. - **move**: flying between the two (0.5s). - **travel**: owned by the page transition. Every slot carries the stream's poster as its own background, so the instant before the feed arrives shows the same picture. **Halls.** The A/B/C switch is a radio group (arrow keys move between halls). Hall A plays the stream; halls marked `false` in `STREAMED` show their photograph from `data-rig-still`, a "Not live" label and their next session time from the programme. Switching repaints the `--now` colour used by now-lines and the current-page marker. On the programme page the picture moves to the chosen hall's lane. **The stream.** It is a muted looping video with `autoplay loop muted playsinline` in the markup: `stage-360.mp4` under 700 pixels wide, `stage-720.mp4` above. There is deliberately no sound control. To show a real live stream, point the video at your provider's HLS address with their player library, or replace the `
