HTML (Hypertext Markup Language) you learn how to create the structure of a web page. It's like building the frame of a house, where you decide where different parts, like the walls, doors, and windows, will go. You use HTML tags to define different elements like paragraphs, headings, images, links, and more. In CSS (Cascading Style Sheets), you learn how to make your web page look good. It's like painting the walls, choosing the furniture, and adding decorations to your house. With CSS, you can change the colors, fonts, spacing, and layout of your HTML elements to make them visually appealing and organized. So, HTML gives your web page structure, while CSS makes it look nice and presentable. Together, they're the basic tools you need to create websites.
