difference between id and class in css

/* The difference between an ID and a class is that an ID 
is only used to identify one single element in our HTML. 
IDs are only used when one element on the page should have a 
particular style applied to it. However,
a class can be used to identify more than one HTML element. */

css difference between class and id

/* 
Syntax: Id uses # while Class uses .
Selector: Only one Id can be attached to an element while multiple classes can be attached to an element.
Uniqueness: Id is unique in a page and can only apply to at most one element while class can be applied to multiple elements so it could be multiple times on a single page.
