PreCSS lets you use Sass-like markup and staged CSS features in CSS. PreCSS combines Sass-like syntactical sugar — like variables, conditionals, and iterators — with emerging CSS features — like color functions, logical and custom properties, media query ranges, and image sets.

css-line-break - A JavaScript library for Line Breaking and identifying Word Boundaries, implementing the Unicode Line Breaking Algorithm (UAX #14)

•    Javascript

---

Line breaking, also known as word wrapping, is the process of breaking a section of text into lines such that it will fit in the available width of a page, window or other display area. The Unicode Line Breaking Algorithm performs part of this process. Given an input text, it produces a set of positions called "break opportunities" that are appropriate points to begin a new line. The selection of actual line break positions from the set of break opportunities is not covered by the Unicode Line Breaking Algorithm, but is in the domain of higher level software with knowledge of the available width and the display size of the text. In addition, the module implements CSS specific tailoring options to line breaking as defined in CSS Text Module Level 3.
