Html text reflow justify3/10/2024 This is solved by wrapping each possible last line in a element. However, this presents a problem for the actual last line of each paragraph, since it is now also justified instead of left aligned. Since every line has an explicit line break, justification needs to be enabled using text-align-last: justify, and word-spacing: -10px is used to avoid additional automatic line breaks due to slight formatting differences between browsers. Media queries are then used to selectively show the line breaks specific to a given column width. The key is to wrap all the potential line breaks (inserted via ::after pseudo-elements) and hyphens in elements that are hidden by default with display: none. It turns out that it is possible to pre-calculate line breaks and hyphenation for specific column widths in a manner that can be encoded in HTML and CSS, as long as web fonts are used to standardize the text appearance across various browsers. A JavaScript library already exists to emulate this, but it adds extra complexity and is a bit slow. This got me wondering whether or not it’s possible to emulate this with plain HTML and CSS. 1 However, it doesn’t emulate the Knuth–Plass line breaking algorithm, which is one of the things that makes L aT eX look good. I recently came across a CSS library for emulating L aT eX’s default appearance. However, as of the time of writing, no browsers supported this property. CSS Text Module Level 4 standardizes the current behavior as the default with a text-wrap property while introducing a pretty option, which instructs the browser to use a higher quality line breaking algorithm. While CSS originally never specified what sort of line breaking algorithm should be used, browsers all converged on greedy line breaking, which produces poor-quality typography but is fast, simple, and stable. In particular, line breaks and hyphenation need considerable improvement. Although slowly improving, typography on the web pages is considerably lower quality than that of high-quality print / PDF typography, such as that produced by L aT eX or Adobe InDesign.
