A new web library called Justif implements advanced Knuth-Plass text justification and microtypography directly in the DOM using dynamically adjusted HTML span elements. The developer utilized large language models to rapidly build the tool, which has been highly praised by the community for solving the notoriously poor text justification quality of standard web browsers. Although currently limited to rectangular text blocks, the underlying engine shows promise for eventually supporting irregular text shapes such as wrapping around images.
