Margin — A Long-Read Newsletter
A reader with a glowing book, circled by rings of light that speed up and brighten as your cursor gets close.
A long-read newsletter and reading club's site. Five animated rings of light orbit a reader with a glowing book and quicken as the pointer nears it; then a sign-up with live validation, a topic marquee, what members get, a filterable issue archive, a quote carousel, membership tiers with club nights and the closing call to action. It is one self-contained HTML file — inline CSS and JavaScript, no framework and no build step — with one AI-generated hero image. Under the hood: Vanilla JS, animated SVG light-trail rings with comet heads over the hero art, split-line serif headline reveal, IntersectionObserver staggered reveals, glass nav that condenses on scroll. What a visitor can do: move the pointer toward the glowing book to speed up and brighten the rings, subscribe with live validation and an animated success state, filter the issue archive by topic, browse reader quotes in an auto-advancing carousel. Best for: Newsletters, Writers & editors, Book clubs, Independent publishers. The exact image prompts are included, so the art can be regenerated or restyled with any image model.

Questions about Margin
Who is Margin for?
Margin is for designers, developers and agencies who want a site that moves like film and doesn't look like a template. Ask your AI to make it about your brand and it rewrites the copy, colours and images around the same build.
What is Margin built with?
Margin is built with HTML/CSS/JS. The source is a single HTML file: open it in a browser and it runs, with no build step. The prompt is written for coding agents such as Claude Code, Cursor and Antigravity.
Can I use Margin for a client project?
Yes. Every purchase includes a commercial licence: use it in your own projects and in work you deliver to clients, including paid client work, change and rebrand it, and publish the result with no credit needed. What you can't do is resell, share or republish the prompt or the source files themselves.
Should I buy the prompt or the source?
The prompt is the written brief that built the design: paste it into a coding agent such as Claude Code, Cursor or Antigravity and it builds the site on your computer, which you then refine. The source is the finished project itself, ready to run exactly as the preview shows. The source always includes the prompt.
Will the prompt give me exactly the preview?
Not exactly, and that's expected. A prompt is a starting point: AI output varies between tools and between runs, so plan to refine spacing, timing and copy. The source pack is the preview itself, finished and running.
Can I get a refund?
Single designs are final once delivered, unless something is wrong on our side: a broken or empty download, a pack that isn't what its page describes, or a double charge. Then email support@brandmotion.in with your receipt and we fix it or refund it. The full terms are on the refunds page.
