How do website rendering happens

Question

Accepted Answer

Website rendering is the process of displaying web content on a browser by interpreting HTML, CSS, and JavaScript.

When a user enters a URL, the browser sends a request to the server for the website's files.
The server responds with the HTML, CSS, and JavaScript files needed to render the website.
The browser parses the HTML to create the Document Object Model (DOM) and the CSS to create the CSS Object Model (CSSOM).
The DOM and CSSOM are combined to create the render tree, which is used to layout and paint the content on the screen.
JavaScript is executed to add interactivity and dynamic content to the website.
The final rendered website is displayed to the user in the browser.
Examples: Chrome rendering engine - Blink, Firefox rendering engine - Gecko, Safari rendering engine - WebKit
