What is the difference between HTML and CSS?

HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets) are two essential languages used in web development, but they serve different purposes.

HTML is used to structure the content of a webpage, such as text, images, and links. It provides the foundation for a webpage's layout and organization.

On the other hand, CSS is used to style the content that is structured using HTML. It allows developers to specify the presentation of elements on a webpage, such as colors, fonts, sizes, and spacing.

In summary, HTML is responsible for the structure and content of a webpage, while CSS controls its visual appearance and style.
