How does a web browser interpret and render HTML code?

Parsing:

When you enter the URL of a web page in the web browser, it downloads that page.

Once downloaded, the browser breaks down the HTML code into the structure of the web page, this is called “parsing“.

Creating the DOM:

The browser creates a DOM (Document Object Model), which displays the HTML document like a tree.

This DOM is of a hierarchical type, in which each HTML element is represented as a node.

Rendering:

Once the DOM is ready, the browser starts to display it.
The browser also uses CSS (Cascading Style Sheets) code to display the DOM.
This continues until the entire page is displayed.
During this process, the web browser interprets HTML, CSS, and other related files and blends them to display them in one form, giving you a consistent and responsive web page experience.
