title: Viewport meta tag in css
body: <p>In viewport meta tag in CSS for achieving responsive web design we set width = device-width like <code>&lt;meta name="viewport" content="width=device-width"&gt;</code> so that the page's width equal to that of the device's width , so that users do not have to scroll to see the page but what about the height ? Does the browser infer the height based on the width and make it device-height ???</p>
