In this video i will talk about how to Change CSS Classes in JavaScript.

Method 1: className property

The className property sets or returns the class name of an element (the value of an element's class attribute).

Tip: A similar property to className is the classList property.

Method 2: classList property

The classList property returns the class name(s) of an element, as a DOMTokenList object.

This property is useful to add, remove and toggle CSS classes on an element.

The classList property is read-only, however, you can modify it by using the add() and remove() methods.

Cross-browser solution: The classList property is not supported in IE9 and earlier. However, you can use the className property or regular expressions for a cross-browser solution (see "More Examples" on the bottom of this page).
