Feature Description

What does this add?

A developer-focused commit history timeline with a vertical connector line, color-coded dots by commit type, monospace hash badges, author names, and relative timestamps. Includes staggered slide-in animation and hover effects.

How does a developer use it?

<div class="ease-commit-timeline">
  <div class="ease-commit">
    <div class="ease-commit-dot ease-commit-dot--feat"></div>
    <div class="ease-commit-content">
      <div class="ease-commit-title">feat: add authentication module</div>
      <div class="ease-commit-meta">
        <span class="ease-commit-hash">c7a91f2</span>
        <span class="ease-commit-author">Ishita Sharma</span>
        <span class="ease-commit-time">2 hours ago</span>
      </div>
    </div>
  </div>
</div>
Why does it fit EaseMotion CSS?
Pure CSS commit timeline with staggered slide-in keyframes (ease-kf-commit-slide), hover scale + translate effects, 5 color-coded dot variants mapped to commit types, and monospace hash badges. Responsive by default. Respects prefers-reduced-motion.
Demo
- Demo added (demo.html works by opening directly in a browser)
Browser Testing
- Chrome
- Firefox
- Edge
- Safari (optional but appreciated)
Notes for Maintainer
Naming follows EaseMotion conventions — .ease-commit-dot--{type} modifier for color variants. Dot colors are consistent with conventional commit types (feat=purple, fix=red, docs=blue, refactor=green, chore=amber).
