HTML Formatting is the practice of organizing code using spaces, tabs, and newlines to make it readable for humans without altering how browsers render the page.

The Role of Whitespace
In HTML, multiple spaces or line breaks are treated as a single space by the browser. Developers utilize this "ignored" whitespace to structure the code visually, making parent-child relationships obvious.
Why We Need It
Without formatting, code becomes a dense, unreadable block. Formatting allows engineers to quickly scan the document, identify layout bugs, and understand the structural flow of the application.
How It Is Achieved
While it can be done manually, formatting is almost universally handled by automated tools (beautifiers or formatters) that parse the code and apply mathematical rules to align tags.
Conclusion
Maintaining a high standard of HTML structure is crucial for any professional web project. Use automated tools to enforce these practices efficiently.
