ID selectors can only be used once per page

Question

I don’t understand this? So I can’t color text from multiple IDs? I guess? I don’t know how to phrase my question.
I can only color text if it’s under a class? Multiple times?

“Class selectors work in a similar way. The major difference is that IDs can only be applied once per page, while classes can be used as many times on a page as needed. “

Answer 1

if you want to apply same css to multiple html elements, use class.
just define a class in css, write all stylings and then give that class to all elements you want to style same.

but id will be always unique.
you can not give multiple elements same id.
giving same id to multiple elements will make difficulty in JavaScript part.

Answer 2

elements means HTML elements.

all those tags in html are also known as elements.
