Technical details
- It applies Prettier's default options: 2-space indentation and lines up to 80 characters. They can't be changed.
- Prettier preserves whitespace that affects how text renders, which is why it sometimes breaks tags in unusual ways (for example, with the closing > on the next line).
- The formatter loads the first time you use it, so the first run takes a little longer.
Frequently asked questions
Does it execute the HTML or just format it?
It only formats it as text; the HTML you enter is never rendered or executed, so it's safe to paste code from an unknown source.
