Whether you want to switch Chrome between portrait and landscape view on your device at your leisure, or simply fancy seeing what a Web page would look like upside down, there are a number of ways you can rotate the display content of Google's browser. You'll be able to flip your screen by downloading an app, or making use of your device's features and functions.
Download Chrome extensions such as Flip This and IMG Rotate from Google's Chrome Web Store. The former will allow you to rotate your whole Chrome page in 90 degree increments, while the latter will let you flip individual HTML elements. Read through your chosen extension's instructions before using it. Once you've installed either of these two examples, you'll be able to right-click on the Web page or element you want to rotate and select by how many degrees you'd like to spin it.
Rotate your screen to your desired viewing position if your device is fitted with an accelerometer that flips your display output. As you move your device, the content on your screen will switch between landscape and portrait views. If you're using an older computer running Windows 7, Vista or XP, you can hold down the "Ctrl" and "Alt" keys while pressing one of the arrow keys to rotate your display.
Right-click on the Web page you're viewing and select either "Rotate clockwise" or "Rotate counterclockwise" if you're working with a PDF file in Chrome. As you do so, your file will rotate 90 degrees in the direction of your choice.
You can download apps to rotate and lock the position of Chrome and other programs on Android devices such as Ultimate Rotation Control and Rotation Locker from Google's Play store. The latter will lock apps in place regardless of whether your device is fitted with an accelerometer, meaning your Chrome page will remain in position no matter how much you move your display.
