HTML (Hypertext Markup Language) is the standard markup language used to create and design web pages and applications. It consists of a series of elements or tags that structure content such as text, images, links, and multimedia. These elements are interpreted by web browsers to render the visual layout of web pages.

CSS (Cascading Style Sheets) is a styling language used to enhance the presentation and appearance of HTML and XML documents. It defines styles, such as colors, fonts, spacing, and layout, for web pages. CSS separates the content of a webpage from its design, allowing for consistent and flexible styling across multiple pages.

HTML, CSS, and JavaScript are essential for web development. HTML structures content, CSS styles it, and JavaScript adds interactivity. Together, they create dynamic and visually appealing websites and web applications, enabling seamless user experiences. Each language serves a unique purpose, facilitating the creation of modern and engaging online experiences.

This web application provides two text areas for entering HTML and CSS code respectively. It then uses JavaScript functions to minify the entered code when the corresponding “Minify” button is clicked. The minified code is displayed back in the respective text area.
