Browser extensions are primarily made using which combination of technologies?

Browser extensions are primarily developed using HTML, CSS, and JavaScript because these technologies align perfectly with the structure and functionality required for creating an interactive web application experience. HTML provides the foundational structure of the extension's user interface, allowing developers to define elements like buttons, panels, and web pages. CSS is used for styling those elements, offering flexibility in design and layout, which enhances user engagement. JavaScript adds interactivity and dynamic behavior, enabling extensions to respond to user actions, manipulate web page content, and communicate with web APIs.

The combination of these three technologies allows developers to build extensions that can effectively integrate with browsers, manipulate browser tabs, or interact with web pages, thus delivering a seamless user experience. This trio is a staple in web development, making it the logical choice for browser extension development.
