Hi there, I've just released the first version of [cascading], library for writing/generating Cascading Style Sheets (CSS) in Haskell. The API design is inspired by many other projects, including blaze-html, HSP and Yesod's Lucius. [cascading]: http://hackage.haskell.org/package/cascading Features: * Style sheets are monoids and can be MonadWritered. * All non-appendix properties of CSS level 2.1 are implemented and exposed through a type-safe API. It's easy enough to set properties for which no type-safe API exists. See the example below. * Easy to integrate into all monadic web frameworks, easy to interleave stylesheets with framework operations. * Builtin support for web-routes. * Color space awareness through the colour library. * Fully encoding-aware with one caveat: If you bypass PropValue and use ByteStrings as property values directly, then UTF-8 is assumed. Example: stylesheet :: (MonadWriter CSS m) => m () stylesheet = onAll $ do select ["p"] $ do margin . Edges $ [zeroLen] padding . Edges $ [_Em # 1, _Ex # 2] select ["em"] $ do fontWeight BolderWeight select ["ul", "ol"] . below ["li"] $ do borderColor (LeftEdge green) borderWidth (LeftEdge ThickWidth) vendors $ "borderRadius" $= ("3mm" :: PropValue) This results in the following stylesheet: p { margin: 0; padding: 1em 2ex } em { font-weight: bolder } ul li, ol li { border-left-color: #008000; border-left-width: thick; border-radius: 3mm; -moz-border-radius: 3mm; -ms-border-radius: 3mm; -o-border-radius: 3mm; -webkit-border-radius: 3mm } Please visit the [homepage]. Feedback is always welcome. If you find bugs, please don't hesitate to [report] them.
