If you have a unique identifier on a div element called main, how should you reference it in CSS - with div#main or just #main? What is considered best practice?
Considering that only one element can have a specific id, using div#main essentially duplicates the functionality of #main. So, which option is preferred for targeting this specific element?
Additionally, if you are certain that the element is indeed a div, which selector would be more appropriate to use in this case?
It goes against the essence of an id to have to provide additional specifications beyond its unique identifier. The whole point of an id is that there should be only one element with that particular id, rendering further details unnecessary. If there is a need for the id to appear in multiple locations, it would be more appropriate to use a class instead.
