# HTML Formatter

> Format and indent HTML properly, preserving inline elements and whitespace sensitivity.

To format HTML, paste your markup and it is re-indented with proper nesting. Prettier understands which elements are whitespace-sensitive, so it will not insert line breaks that would visibly change how inline elements such as span and a are rendered.

## FAQ

### Why did some tags stay on one line?

HTML treats whitespace between inline elements as meaningful. Prettier deliberately avoids breaking those lines because adding a newline would introduce a visible space in the rendered page.
