Which component of a browser is responsible for displaying web pages?

The layout engine is the component of a browser that is responsible for rendering and displaying web pages. It takes the HTML markup and CSS styles provided for a webpage and processes them to determine how the content should be formatted and presented visually to the user. This involves calculating the dimensions and positions of elements, styling them according to the specified rules, and ultimately painting them onto the screen in a way that users find visually coherent and interactive.

The layout engine also handles various aspects of web page rendering, such as handling responsive design to adapt layouts to different screen sizes, dealing with web fonts, and ensuring that the overall appearance aligns with the intent of the web developers and designers. In contrast, while other components like the JavaScript interpreter, networking component, and UI backend play significant roles in the web browsing experience, they do not directly contribute to the rendering of web content in the way the layout engine does.
