Question about CSS

Question

so p#p01 { color:blue;} and #p01 { color:blue;} have the same results so the question is which is the correct way? With (p#p01) or without (#p01) and why is it the correct way?

Answer 1

#p01 is correct, because css rules applyed on id have highest priority, and also you can't have multiple elements with same ID, so p#p01 is pointless.

Answer 2

i think that both work. but there is just no reason to use first one

Answer 3

wait p#p01 is not correct actually

Answer 4

they both displayed correctly in the test area on w3schools but thats the html tutorial and not html5. that could be why

Answer 5

yeah I didn't think so
