Final answer:
HTML provides the layout and structure, while CSS enhances the webpage with colors, font sizes, and other visual styles.
Step-by-step explanation:
The purpose of HTML (Hypertext Markup Language) is to provide the layout and structure of a webpage. It uses tags to define elements such as headings, paragraphs, lists, images, links, and more. HTML creates the basic structure of a webpage, organizing its content in a logical manner.
The purpose of CSS (Cascading Style Sheets) is to enhance the webpage by adding colors, font sizes, backgrounds, and other visual styles. CSS allows you to apply styles to HTML elements, making the webpage visually appealing and consistent.
In summary, HTML provides the layout and structure, while CSS enhances the webpage with colors, font sizes, and other visual styles.
