Wiring Components

Components are effect snippets — HTML, CSS, and optionally JS that you merge directly into an existing composition. Unlike blocks, components have no standalone timeline; they participate in the host composition's timeline.

General process

1. Run hyperframes add <component-name>
2. Open the installed file (e.g., compositions/components/grain-overlay.html)
3. Read the comment header for usage instructions
4. Copy the parts into your host composition:
5. HTML elements — inside your <div data-composition-id="...">
6. CSS styles — into your composition's <style> block
7. JS setup — into your composition's <script>, before your timeline code
8. Timeline calls — into your GSAP timeline (if the component exposes them)

Example: grain-overlay (CSS-only, no timeline integration)

<!-- Paste the overlay div into your composition -->
<div
  id="grain-overlay"
  style="position: absolute; top: 0; left: 0; width: 100%; height: 100%; pointer-events: none; z-index: 100;"
>
  <div class="grain-texture"></div>
</div>

Then paste the CSS keyframes and .grain-texture rule into your styles. No GSAP timeline calls needed — the grain animates via CSS @keyframes.

Example: shimmer-sweep (needs timeline integration)

See examples/add-component.md for the full shimmer-sweep walkthrough (HTML wrapping, CSS, JS setup, and timeline call).

Key principles

• Components inherit the host composition's dimensions and duration
• Place component HTML at the appropriate z-index relative to your content
• Read the comment header in each snippet for customizable values
• Run hyperframes lint after wiring to catch structural issues
