Learn React - Component Highlighter 作者: CODEGUYAKASH

The fastest way to train your "component-thinking" muscle.

Open any website, toggle the extension ON, and instantly see which HTML elements could be extracted into React components — color-coded with on-hover tooltips.



| Color | Category | Examples |
|-------|----------|----------|
| 🔵 Blue solid border | Layout — big-picture components | <Navbar />, <Header />, <Footer />, <Sidebar /> |
| 🟠 Orange dashed border | Repeated — reusable patterns (3+ siblings) | <Card />, <ListItem />, <ProductCard /> |
| 🟢 Green solid border | Atomic — small building blocks | <Link />, <Button />, <Input />, <Image /> |

1. Click the Learn React icon in your toolbar.
2. Toggle Component Highlighting ON.
3. Browse any website — elements are highlighted in real time.
4. Hover over any highlighted element to see:
5. The suggested React component name (e.g., <Navbar />)
6. A short hint explaining why it should be a component.
7. A legend panel in the bottom-right corner shows the color key.
