What is ID in HTML?

In HTML, the "id" selector is used for the id attribute of an element. For HTML elements, the "id" name starts with the symbol "#" followed by a unique name. An important feature of the id element is that we can only attach an id selector to an element. Therefore, ID selectors are always unique within an HTML page.

What is CLASS in HTML?

In HTML, the "class" selector is used to select elements with a specific class attribute. Class selectors start with a period (.) followed by the class name. Unlike the id selector, we can attach multiple selectors to an HTML element. Therefore, this class can be applied multiple times within a page. An important thing to note about class selectors is that class names cannot start with a number.
