Responsive Design 

Responsive design is an approach to web design in which the interface adapts to the device's layout, facilitating usability, navigation and information seeking.

 

Break Point ? 

Each breakpoint (a key) matches with a fixed screen width (a value) :

• xs, extra-small: 0px
• sm, small: 600px
• md, medium: 900px
• lg, large: 1200px
• xl, extra-large: 1536px

for the simple the break point is like you have created the rule (if-else) that you can display the website, webpage in the different layout.

you can handle to display with many other devices eg. mobile, monitor, tablet

the breakpoint very important concept in the responsive development.

What is Container ?

How to implement responsive design with MUI

import { Box } from "@mui/material";
import "./App.css";

function App() {
  return (
    <>
      <Box
        sx={{
          backgroundColor: { xs: "red", md: "green", lg: "yellow" },
          height: "100vh",
        }}
      >
        Hello World
      </Box>
    </>
  );
}

export default App;

For this code we define the background color into 3 color and 3 breakpoint that mean

background color is "red" : extra small screen 

background color is "green" : medium small screen

background color is ""yellow" : large screen

you can implement this syntax to all CSS property.
