 # overflow
 
-Overflow is a CSS layout engine created to explore the reaches of the foundational CSS standards (that is, inlines, blocks, floats, positioning and eventually tables, but not flexbox or grid). It has a high quality text layout implementation and is capable of displaying many of the languages of the world. You can use it to generate PDFs or images on the backend with Node and [node-canvas](https://github.com/Automattic/node-canvas) or render rich, wrapped text to a canvas in the browser.

+overflow doesn't have any `package.json` dependencies. External code has instead been checked in and modified to varying degrees to fit this project. It's also a way to rebel against `node_modules` insanity. These are the repos that have been used:

+* [harfbuzz](https://github.com/harfbuzz/harfbuzz) does font shaping
+* [Tehreer/SheenBidi](https://github.com/Tehreer/SheenBidi) is used for bidi
+* [foliojs/linebreak](https://github.com/foliojs/linebreak) provides Unicode break indices
+* [foliojs/grapheme-breaker](https://github.com/foliojs/grapheme-breaker) provides Unicode grapheme boundaries
