Expressive, flexible, and powerful stylesheets for native iOS apps.

#Classy

Not CSS. Instead of trying to force UIKit to fit CSS syntax, properties, conventions and constructs. Classy is a stylesheet system built from the ground up to work in harmony with UIKit. It borrows the best ideas from CSS and introduces new syntax, conventions and constructs where appropriate.

Plays nice with Interface Builder and views created in code.

##Supports UIAppearance Classy supports all UIAppearance properties and methods and much more. But instead of being limited to +appearanceWhenContainedIn: and +appearance, Classy gives you much more control over which views are styled and with what values.

##Example Stylesheets

Classy features a very flexible, nestable syntax. Classy makes { } : ; all optional so you can choose a style that suits you. It also saves you from worrying about small syntax mistakes like accidentally forgetting to end a line with a ;

This is a valid stylesheet

$main-color = #e1e1e1;

MYCustomView {
  background-color: $main-color;
  title-insets: 5, 10, 5, 10;
  > UIProgressView.tinted {
    progress-tint-color: black;
    track-tint-color: yellow;
  }
}

^UIButton.warning, UIView.warning ^UIButton {
  title-color[state:highlighted]: #e3e3e3;
}

This is also a valid stylesheet

$main-color = #e1e1e1

MYCustomView 
  background-color $main-color
  title-insets 5, 10, 5, 10
  > UIProgressView.tinted 
    progress-tint-color black
    track-tint-color yellow

^UIButton.warning, UIView.warning ^UIButton 
  title-color[state:highlighted] #e3e3e3
