Frequently Asked Questions

Will formatting change how my page renders?

Almost never. The formatter avoids adding whitespace where it would be significant — inside pre and textarea, and between inline elements where a space would appear on screen.

Why is whitespace significant in HTML?

Because whitespace between inline elements collapses into a single rendered space. That is why breaking a line between two spans can shift the layout, and why the formatter keeps inline runs together.

Does it validate my HTML?

No, it formats. Broken nesting is preserved rather than corrected, since guessing your intent could change the page. Use a validator for conformance checking.
