What is the difference between id and class in html

Question

I need a human's explanation

Answer 1

Firstly class is what is mostly used by CSS/Bootstrap to style the html
Now you can also use id too
But not as popular as using class
Now the main difference is class can be used fo target more than one element in html but an Id can only target one element , Just take your Id like your phone number
It can only be for one person
But class isnt unique

Answer 2

You can have multiple elements with the same class but diffrent ids.
