 			<h2>Viewport meta tag</h2>
-			<p>Note above that there is a meta <code>viewport</code> tag in the <code>head</code> to specify how the browser should display the page zoom level and dimensions. If this isn't set, many mobile browsers will use a "virtual" page width around 900 pixels to make it work well with exisitng desktop sites but the screens may look zoomed out and too wide. By setting the viewport attributes to <code>content=&quot;width=device-width, initial-scale=1&quot;</code>, the width will be set to the pixel width of the device screen. </p>
