What is the difference between classes and IDs in CSS?

Classes and IDs are both used in CSS to apply styles to elements, but they have some key differences:

• Classes: Classes can be used multiple times in an HTML document. This means that you can apply the same styles to multiple elements by assigning them the same class. To apply a class to an element in CSS, you use a period (.) followed by the class name.
• IDs: IDs are used to uniquely identify a single element on a page. This means that each element can only have one ID, and that ID should be unique on the page. To apply an ID to an element in CSS, you use a hash symbol (#) followed by the ID name.

Overall, classes are more versatile and can be used multiple times, while IDs are used for unique identification of elements on a page.
