HTML is the language that structures the content of web pages.
In Depth:HTML (HyperText Markup Language) is the standard language used to create and structure content on the web. It defines the meaning and structure of text, images, links, and other elements on a web page. Web browsers read (or "render") HTML files and display them as the pages you see online.
HTML is not a programming language — it’s a markup language that describes what each piece of content is, such as a heading, paragraph, image, or link. Modern HTML includes semantic elements that improve accessibility and SEO, and supports multimedia, forms, and more.

CSS is the language used to style and design the appearance of web pages.
In Depth:CSS (Cascading Style Sheets) controls the layout, colors, fonts, and overall visual presentation of web pages. While HTML defines the content and structure, CSS defines how that content should appear.
CSS allows you to create beautiful, responsive designs and maintain a consistent style across multiple pages with external stylesheets. Modern CSS includes advanced features like animations, transitions, flexbox, grid layouts, variables, and media queries for responsive designs.
