> The other value of pretty specifically addresses preventing orphans and can be more broadly applied. The algorithm behind pretty will evaluate the last four lines in a text block to work out adjustments as needed to ensure the last line has two or more words. This is very, very badly wrong. `text-wrap-style: pretty` is explicitly not about orphans and does not have a defined algorithm. It’s about prettiness, a subjective thing that will have different interpretations in different browsers and over time, and this is extremely deliberate. What the author has described is what Chromium has implemented at this time. All the spec says is <https://www.w3.org/TR/css-text-4/#valdef-text-wrap-style-pretty https://www.w3.org/TR/css-text-4/#valdef-text-wrap-style-pre...>, that `text-wrap-style: pretty` “Specifies the UA should bias for better layout over speed, and is expected to consider multiple lines, when making break decisions. Otherwise equivalent to auto”. TAG review of the feature requested that implementers use at least two heuristics, “to avoid authors using it as a proxy for a more specific thing” <https://github.com/w3ctag/design-reviews/issues/864#issuecomment-1655290020 https://github.com/w3ctag/design-reviews/issues/864#issuecom...>. For total clarity: ‘pretty’ is not necessarily any different from ‘auto’, and ‘auto’ is permitted to do exactly the same thing as ‘pretty’ does, and I hope and expect that browser makers will eventually go that direction for most contexts (contenteditable/<textarea> being the main exception, and maybe lower-powered platforms). If you explicitly want a greedy/first-fit technique, use `text-wrap: stable`. Firefox has had a bug open for 13 years where shifting in this direction and using Knuth–Plass almost everywhere has been seriously contemplated <https://bugzilla.mozilla.org/show_bug.cgi?id=630181 https://bugzilla.mozilla.org/show_bug.cgi?id=630181>, long before text-wrap-style.
