Responsive Viewport Meta Tag

<meta name="viewport" content="width=device-width"/>

Which means “browser, render this website exactly as wide as you are naturally.”

<meta name="viewport" content="width=device-width, initial-scale=1.0"/>

The initial-scale=1.0 part sets the initial zoom level when the page is first loaded by the browser.
