- gvadtech 9y agoWell, the users are actually tracked with server-side script (PHP in your example). How it is different from tracking users with HTML? Besides the fact that "CSS selectors ensures that the URL is only called when an action is performed". Or using plain JS. The only benefit is ability to track with JS disabled and only after certain action is performed. But the title is misleading
- 777lisa 9y ago"It can also be used to extract the user’s IP address, user agent, and other identifying information." Not super shocking, given that most JS libs will gather this type of information, but very interesting to see this done via CSS which isn't monitored as easily.
