Introduction

HTML pages must look good on phones, tablets, and desktops. Developers use a special viewport meta tag to control the page scaling. CSS media queries then adjust the layout based on the screen width.

Syntax

1<!-- responsive meta tag -->
2<meta name="viewport" content="width=device-width, initial-scale=1.0">

Example

1<!-- this sets the viewport -->
2<!DOCTYPE html>
3<html lang="en">
4  <head>
5    <meta charset="UTF-8">
6    <meta name="viewport" content="width=device-width, initial-scale=1.0">
7    <title>Responsive</title>
8  </head>
9  <body>
10    <p>This text fits the screen.</p>
11  </body>
12</html>
