It is value noting that inline kinds have a excessive precedence over different kinds. So if you happen to had an exterior stylesheet with any formatting, it might be overridden by the inline type.
It is a demonstration of inline styling in a React app.
import React from 'react';
import ReactDOM from 'react-dom/consumer';
const Header = () => {
return (
<>
<h1 type={{backgroundColor: "lightblue"}}>Hi there World!!!!!</h1>
<h2>Add just a little type!</h2>

}You possibly can import the CSS module onto your App.js as follows;
import { React } from "react";
import kinds from "./kinds.module.css";
perform App() {
return (
<h1 className={kinds.heading}>Hi there Geekflare reader</h1>
);
}
export default App;Advantages of utilizing CSS modules
- Simply integrates with SCSS and CSS
- Avoids class identify conflicts

To begin utilizing Styled Elements, you’ll be able to set up the bundle in your root folder with this command;
npm set up styled-componentsThe subsequent step is to import styled elements into your React app

peak: 120px;
background-color: lightblue;

`;
return <Wrapper />;
}
export default App;Within the rendered app, the above kinds are imported from Styled Elements.

npm set up node-sassYou possibly can then create your recordsdata and provides them a .scss or .sass extension. You possibly can then import your recordsdata within the regular method. For instance;
import "./Elements/App.sass";Advantages of SASS/SCSS
- It comes with many dynamic options similar to mixing, nesting and increasing.
