1. **Parsing**: The browser parses the HTML document from top to bottom, identifying and interpreting each element and its attributes. It builds a Document Object Model (DOM) tree, which represents the structure of the web page as a hierarchical collection of nodes. Each node corresponds to an HTML element, such as a heading, paragraph, image, or link.

2. **Rendering**: The browser uses the DOM tree to render the web page on the screen. It determines the layout of the page, including the position and size of each element, based on the **CSS** styles applied to the elements. The browser also calculates the visibility of each element, taking into account factors such as z-index, opacity, and overflow.
