It works alongside technologies like Cascading Style Sheets (CSS) and JavaScript. CSS (Cascading Style Sheets): A style sheet language used to define the presentation of documents written in HTML or XML. CSS is a core technology of the web, enabling developers to customize the appearance of web pages. JavaScript (JS): A versatile programming language that powers web page behavior on the client side. As of 2022, 98% of websites use JavaScript, often alongside third-party libraries. HTML is essential for structuring web documents (web pages), while CSS defines their appearance.
