While running a MERN app on firefox, got this error in browser console and css is not loaded: `The stylesheet http://localhost:3000/src/css/component.css was not loaded because its MIME type, “text/html”, is not “text/css”`

I am adding CSS to `index.html` like this :

```
 <link rel="stylesheet" type="text/css" href="../src/css/component.css" />

```

Where am I going wrong ?

What are the other ways to add external css for sections apart from the React components ?
