What is an HTML Formatter and Why Use It?

An HTML Formatter (also known as a Beautifier) is a tool that organizes a page's source code to make it readable. It applies consistent indentation rules, wraps long lines, and structures tags hierarchically, making it easier to identify element opening and closing errors.

The Importance of Visual Structure

Although the browser can read "dirty" or spaceless HTML, for the developer, well-formatted code is vital for:

Debugging: Quickly locating where a <div> ends.
Accessibility: Ensuring the hierarchy of headings (H1-H6) and semantic elements is correct.
Collaboration: Maintaining a project standard in teams using version control tools like Git.

Formatter vs. Minifier

While the formatter focuses on human readability, the minifier focuses on machine efficiency. During development, we use the formatter; before sending to production, we use the minifier to reduce load times.
