litherum has just created a new issue for https://github.com/w3c/csswg-drafts: == [css-text-4] Allow for paragraph-level line breaking == There are a few algorithms which attempt to choose line breaks within a paragraph in order to maximize the beauty of the paragraph as a whole. Such algorithms try to do some subset of: * Minimize hyphenation * Minimize extra space at the end of each line (or between words for justified text) * Minimize rivers * Minimize widows/orphans * Minimize two hyphenated lines in a row * Minimize visual differences between adjacent lines * Minimize single-syllable or single-word last lines * For paginated media, minimize single lines at the beginning or end of pages * More? Obviously, it is impossible to satisfy all these desires simultaneously for arbitrary paragraphs. The exact algorithm should not be specced for these reasons: * Browsers should be allowed to innovate with heuristics of deciding how hard to try to solve one item at the expense of the other items * Browsers should be allowed to teach and improve their implementations about new typographical conventions as time goes by * Criteria for beautiful paragraphs are locale- and language-specific * Different user agents may wish to provide different thresholds of participation (e.g. only consider a sliding window of n lines, or bail after x milliseconds of compute time, etc.) Instead, there should be a way for a web author to opt-in to paragraph-level layout for beautiful paragraphs. I'm not sure what the best mechanism for this is. Perhaps a new value to the text-wrap property? Perhaps a new property? Perhaps something else?
