Sorted list of cursors and added missing types, updated total count from 36 to 39. Added note about using auto (default) with URL cursor in case file is unavailable on page load.
I noticed most of the pseudo-selectors/pseudo-elements are missing from this section, so I created a basic document as a starting point for the ::after pseudo-element. I tried to follow the same layout and style as the other articles in this section. This document is meant to be a start and added to/expounded on.
It's also my first real pull request - so please let me know how I can improve if needed 👍
* Fix: Adjust colour description to images
The text says that the gradient goes from red to yellow, but in all pictures, the gradients go from red to green. I substituted "yellow" by "green" in the text.
I also added a new resource for learning more.
* Improved "More Information" section
