CustardUI

Rich, layered interactivity for static websites with no backend required.

CustardUI (formerly CustomViews) is a lightweight, framework-agnostic runtime that adds dynamic, memory-persistent UI components to any static site. Built for educational websites, documentation portals, and course textbooks where one size never fits all.

What it does

• Toggles — let readers show, hide, or peek sections based on their preferences
• Synced Tabs — tab selections persist across the entire site and across visits
• Placeholders — personalize text with reader-defined values like names or team IDs
• Focus & Share — highlight and link directly to any content block on the page
• Adaptations — serve entirely different audiences from a single deployment, swapping images, links, and text per organization

Getting started

Add the script tag to your base layout:

<script src="https://unpkg.com/@custardui/custardui" data-base-url="/"></script>

Add a custardui.config.json to your site root, then start using <cv-toggle>, <cv-tabgroup>, and [[placeholders]] in your pages.
