My concept involves utilizing a jQuery snippet (I prefer JQuery over regular javascript due to my comfort level with it) that is able to identify when it is executed on a profile page with a specific URL format like "" (just for demonstration purposes). Once the snippet recognizes that it is on a profile page, it will retrieve data from a designated (likely hidden) element, apply CSS tags to this data, and add it to the header section of the current document.
Essentially, I am attempting to develop a system for personalized profile customization where users can generate their own CSS styles. One of the main challenges I am facing is determining how to enable the snippet to identify the URL on which it is being executed. Is there a function within jQuery capable of accomplishing this task?
