WebKit is an open-source web browser engine that powers several popular web browsers, including Safari and Google Chrome (in its earlier versions). It is responsible for rendering web pages, meaning it interprets HTML, CSS, and JavaScript to display content correctly on screens. WebKit was originally developed by Apple and has become a key component in the development of web technologies. WebKit supports various web standards, ensuring that websites function consistently across different platforms and devices. Its architecture allows for fast performance and efficient memory usage, making it suitable for both desktop and mobile environments. Developers often use WebKit to create responsive and visually appealing web applications.
