In the second exercise of the “Hover States and Cursors” lesson it is stated that:
Add a declaration to also change the cursor to
pointer. Even though this behavior is seen when the mouse is hovered over, you should add it to the rule for all
<a>tags, as the browser will only change cursor styles on hover by default. Putting the rule on an
a:hoverrule can cause unwanted behavior in some cases.
I have tried to search in Google but it yielded no relevant results (just this question in another forum with no clear answer), what could happen if cursor:pointer is located inside :hover?
