-> Due to the magic that is HTML parsing (quote from [DOM spec](https://dom.spec.whatwg.org/#introduction-to-the-dom)), there do exist certain places where whitespace characters could be ignored.

However, CR characters can also be inserted into the DOM either via [character references](/en-US/docs/Glossary/Character_reference) or JavaScript, so the CSS whitespace processing rules still need to define how to handle them.
