jQuery Manipulating CSS. jQuery has several methods for CSS manipulation. We will look at the following methods: addClass() - Adds one or more classes to the selected elements. removeClass() - Removes one or more classes from the selected elements.
The addClass () method adds one or more class names to the selected elements. This method does not remove existing class attributes, it only adds one or more class names to the class attribute. Tip: To add more than one class, separate the class names with spaces.
A function returning one or more space-separated class names or an array of class names to be added to the existing class name (s). Receives the index position of the element in the set and the existing class name (s) as arguments. Within the function, this refers to the current element in the set.
