Tracking Events Responsively With The New Google Analytics

This one is about capturing the width of the viewport through Google Analytics. Basically GA will only track the device width. This is fine for tablet and phone because it’s rare (or is it even possible at all) to change the width of the browser other than full screen. 

With laptops and monitors though you can change the width based on your particular setup. This tip will allow you to track the width of the browser, rather than just the device.
