Using W3.CSS
Another way to create a responsive design, is to use a responsive stylesheet, like W3.CSS, which you REALLY don't want to look at!! This style sheet makes it easy to develop webpages that look nice at any size; desktop, laptop, tablet, or phone. Have a look at this responsive webpage designed using the following HTML file:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="w3.css">
</head>
<body>
<div class="w3-container w3-orange">
<h1>W3.CSS Demonstration</h1>
<h3>Resize this responsive page!</h3>
