In short: ID is used for a single element, Class is used for multiple element. Generally... they are used for CSS and JS.

Another difference -well not difference but a consequence- is that getElementById can only get one element wereas getElementByClassName can get as many as you have.

`id` can be used for once in a webpage, while `class` can be used in many places in same webpage. These are used for CSS
