Is it necessary to use class or id tag in css

Question

I want answer fast pkease

Answer 1

Yes, you need them to reference to multiple elements (with "class", for example all the <p> elements) or a single specific elements (with "id", for example a single <div>).

Answer 2

you need these because if you want for example only a <p> or a bunch of <p> and you have many of <p> you need something to specify them!

Answer 3
