    Are hypens no longer acceptable?

    There is no mention of it in the post. If words (in any language) can be arbitrarily long and columns can be arbitrarily narrow, we will need to solve for this anyway.

    Even without those extremes, I feel that there will always be place for the good old hypen when displaying or printing text for the main purpose of readability. No need to max out on perfect "look" in every application of text.

    In fact in many places one might even find columns with jagged right edges more readable -- letting you visually distinguish each line from the one above/below it easily by length alone -- and may even lend a certain aesthetic character that is the opposite of mechanical / boring / machine produced / sterile.

    Of course not negating the need for a well implemented method without bugs to justify text correctly when the use case demands it.

        What is an example of a "high-end page-layout program" referenced in that document? I mean, of course I assume they exist for professional type setting, book publishing and such, but I have never seen or heard of the actual software.

            We used Adobe InDesign at my last work, which I believe is an industry standard. Affinity Layout if you don’t want to sell your kidney to Adobe. Scribus is an open source project but I’m not sure how the quality is in that.

            • omnimus 4 minutes ago

              There is only Adobe InDesign. Even though you can make high quality layouts in other programs (Affinity, Scribus) once you get to actually printing in pro printer the whole pipeline is InDesign. It's Adobes secret money printer, software that many don't realize it rivals Photoshop in usage.

              Thanks for that link! There is a bit more ... justification (pun intended) on that page for this recommendation to turn-on hypenation; and also some valuable advice on choosing spacing between words over spacing between letters.

              Auto-hyphenation is part of what text-wrap: pretty does.

              • notpushkin 4 hours ago

                No, it’s not. You can turn it on or off independently.

              The example for "avoid short last lines" has a short last line - if that was intentional, a great touch by the writer!

              • iamtedd an hour ago

                That depends on the width of your browser. On my mobile, nearly every paragraph had one word or part of a word as the last line.

                It reminds me of one of my favorite programs, par[1].

                  I’m looking at the comparison [0] and the `pretty` example is hyphenated, while greedy is not. Not sure it’s fair to compare them like that, considering we’ve had `hyphens: auto` for a while now.

                  Edit: it’s actually vice versa! Which I should have known because the very next paragraph says:

                  > But the “smart” algorithm decides to add an entire line to it, which requires inflating all the white space proportionally.

                  Which is exactly how the example on the right looks.

                  • crazygringo 4 hours ago

                    That jumped out at me too... I'm not sure if they have different hyphenation properties set though, or if the greedy justified version just doesn't wind up hyphenating anywhere in this particular case?

                    Unfortunately there's no live HTML demo to inspect, just the images.

                    • notpushkin 4 hours ago

                      Just found this demo in the Safari blog post: https://cdpn.io/pen/debug/xxvoqNM

                      • crazygringo 4 hours ago

                        Fascinating, thank you!

                        Playing around with it, seems that Safari simply stops hyphenating entirely when when text-wrap is pretty, regardless of whether it's justified or not. (If you smoothly resize the browser width, it makes it pretty easy to tell if hyphens ever come up.)

                        Which means the image on the left seems like it might be the wrong image?

                        And now I wonder if text-wrap: pretty is supposed to avoid hyphenation? Are hyphens not pretty? Or is it just a partial implementation by Apple, that they haven't gotten around to supporting hyphenation for it yet?

                        • notpushkin 4 hours ago

                          You can get it if you carefully adjust the window width! Or there’s one example in the author’s post – the word “implementation” is hyphenated for me [1].

                          So it looks like the algorithm tries to minimize hyphenation, which makes sense to be honest.

                          [1]: https://matklad.github.io/2026/02/14/justifying-text-wrap-pr...

                          • crazygringo 3 hours ago

                            Ha. Oh wow. OK, I got "implementation" to hyphenate... but only once I changed the zoom level, and only for one specific exact window width. One pixel narrower or wider, and it stopped hyphenating.

                            So hyphenation exists in theory, but I'm just going to go ahead and say that however it's tuned seems completely broken.

                            • notpushkin 3 hours ago

                              Again, I think it’s very deliberate :-) Hyphenated words are slightly harder to read, so it makes sense to avoid them – maybe not as zealously, though.

                      Um, no? Chrome shipped this feature in 2023: https://developer.chrome.com/blog/css-text-wrap-pretty

                      Safari isn't early shipping this, they're late. Though not as late as Firefox, admittedly.

                      • notpushkin 4 hours ago

                        Hmm, I’m looking at the demo in Chrome and don’t see any difference when I turn on `pretty`: https://cdpn.io/pen/debug/xxvoqNM

                        In Safari, it’s a very different look.

                        • crazygringo 4 hours ago

                          Yeah, very weird.

                          Caniuse claims it's supported in Chrome: https://caniuse.com/mdn-css_properties_text-wrap_pretty

                          But you're right, it very clearly isn't working.

                          Is it a regression? Did it break and nobody noticed?

                          • no_news_is 3 hours ago

                            From https://webkit.org/blog/16547/better-typography-with-text-wr...

                            "While support for pretty shipped in Chrome 117, Edge 177, and Opera 103 in Fall 2023, and Samsung Internet 24 in 2024, the Chromium version is more limited in what it accomplishes. According to an article by the Chrome team, Chromium only makes adjustments to the last four lines of a paragraph. It’s focused on preventing short last lines. It also adjusts hyphenation if consecutive hyphenated lines appear at the end of a paragraph."

                            The article goes on to talk about how it's up to the browser (and not necessarily permanent) about how to handle the setting, and furthermore a new value was agreed upon to do what Chromium was doing, called "text-wrap: avoid-short-last-lines".

                            Here's the article on what the Chromium version does: https://developer.chrome.com/blog/css-text-wrap-pretty/

                            • crazygringo 3 hours ago

                              Ah, OK. I finally got the demo to show a difference under one specific window width, where it changed the last line of a paragraph from one word to two words.

                              So it does exist... but yeah, barely does anything. Thank you for finding the explanation!

                                Amazing summary. Thank you so much!

                                I think the answer is in the post:

                                > Although Safari is the first browser to ship a non-joke implementation of text-wrap

                                (Emphasis mine.) Chrome is using a different algorithm for this, which probably fixes some typographic problems, but defaults to greed most of the time.

                                • crazygringo 3 hours ago

                                  Interesting. As far as I can tell, Chrome isn't doing anything different. I can't find any window width where the checkbox makes any difference.

                                  Edit: finally found it, see cousin comment.

                              So only 42 years after TeX instead of 44.

                              One less gripe out html I guess. Still a few hundred left.

                              While the broader point is fine, the example to me is just bad to me: very narrow column with a lot of hyphens and identical width/no variety making it harder to anchor your eye (though colored letters are awesome and play this role)

                              Ok, bad rag is bad, but the ancient text goes overboard in the other direction. This looks close to the form-over-function vibe.

                                  I'm not entirely up on all the abbreviations and and shorthand used in medieval manuscripts, but the macron over the final ū in 'capitulū' indicates the vowel being nasalized, which often happens before the final 'm' consonant which in this case is suspended. The 'pmū' is similar, but also I think a contraction or abbreviation for primum. With all these tricks available to the scribes it's no wonder they can make the right edge look nice.

                                    It's latin. "de omnibus" on the second line is pretty well recognizable. But holy hell is Gutenberg's font terrible. Look at the first word on the second line, it ends in seven undotted sticks that seem to bleed over into each other a bit. I read that as "mim" before I figured out it was "num".

                                    Anyway, it's the Gutenberg bible. The epistle of St. Jerome, according to the alt text.

                                    Justified text is really not good, yeah. `text-wrap: pretty` works fine with left-aligned text though!
