Why `img src` isn't enough. Styling and animating SVGs by inlining them in React.
If you use `<img src="icon.svg" />`, you can't change its color with CSS on hover.
### Inline SVG
`<svg fill="currentColor" ... />`
Now the icon inherits the text color.
`className="text-red-500 hover:text-blue-500"`
This allows for dynamic theming (Dark Mode) without loading multiple icon files.
