The toggleClass() method is used to add or remove a CSS class automatically.
If the class exists, it removes it.
If the class does not exist, it adds it.
This method is very useful for toggling active states in buttons, menus, and themes.
Each call switches the class state automatically.
This toggles the class when the button is clicked.
This is commonly used for active menu highlighting.
