HTML (Hypertext Markup Language), CSS (Cascading Style Sheets), and JavaScript are the three fundamental technologies that make up the World Wide Web. They are the building blocks that help creating website structure, style, and functionality.


HTML is the standard markup language used for creating web pages. It provides the structure and content of a web page by using a set of elements and tags. HTML elements describe the content's meaning, while tags are used to format and style the content. For example, the <h1> tag is used to define headings, while the <p> tag is used to define paragraphs.


CSS is used to style and format HTML content. It allows web developers to separate the presentation of a web page from its content, making it easier to maintain and update. CSS can be used to control the layout, font, color, and other visual aspects of a web page. It provides a more sophisticated way to style web pages than HTML's basic formatting capabilities.


JavaScript is a high-level, scripting programming language that adds interactivity to web pages. It can manipulate HTML and CSS and perform actions in response to events, such as a button being clicked or a page being loaded. JavaScript can also be used to validate user input, create animations, and update content without reloading the page, making web pages more dynamic and user-friendly. Over the years the language slowly found its place in other areas like back-end programming, hardware and IoT technologies.

In conclusion, HTML, CSS, and JavaScript are the essential components of every web application, and they work together to create interactive and visually appealing web pages. Understanding these technologies is crucial for front-end web development and building the web as we know it today.
