What are class and div used for ?

Answer 1

HTML - Div Element(s) The <div> tag is nothing more than a container unit that encapsulates other page elements and divides the HTML document into sections. Web developers use <div> elements to group together HTML elements and apply CSS styles to many elements at once.

Answer 2

class: The class selector is used to specify a style for a group of elements. Unlike the id selector, the class selector is most often used on several elements. This allows you to set a particular style for many HTML elements with the same class.
