- Build a reusable web component that exposes a clean API.
- Ensure accessibility with ARIA attributes and keyboard support.
- Optimize for performance with Shadow DOM and lazy rendering.
- Provide theming and responsiveness without coupling to a framework.
- Include tests and a small build setup to run locally.
Key outcomes:
- A drop-in profile-card web component you can ship in multiple apps.
- Clear separation between component logic, styling, and data.
- A guide to extending the component with additional slots, props, or micro-interactions.
You can use this component in your HTML like this:
<profile-card id="pc" name="Alex" title="Engineer">
<span slot="bio">Custom bio here.</span>
<span slot="social">Twitter: @alex</span>
</profile-card>
This component uses a Shadow DOM to encapsulate styles and prevent leakage. It also uses CSS variables for theming and ARIA attributes for accessibility.
