stylus-skeuomorphic

skeuomorphic UI parts generated by stylus.

Quick Start

Installation

$ npm i stylus sylus-skeuomorphic

Usage

1. make config or use presets with skeu-config function.

config = {
  name: 'gray',
  material: {
    duration: 100ms,
    texture: {
      type: 'flare',
      times: 5,
      opacity: 0.2
    },
    bg_color: white,
    vignette_effect: 0.1,
    diffusion: 0.1,
    top: {
      blend: 0.25,
      alpha: 0.8
    },
    bottom: {
      blend: 0.15,
      alpha: 0.5
    }
  },
  normal: {
    theme_color: #aaa,
    lightness_mod: -25,
    saturation_mod: 0,
    spin_mod: 0deg,
    txt_color: white
  },
  hover: {
    theme_color: #999,
    lightness_mod: -37,
    saturation_mod: 0,
    spin_mod: 0deg,
    txt_color: #222
  },
  active: {
    theme_color: #888,
    lightness_mod: -40,
    saturation_mod: 0,
    spin_mod: 0deg,
    txt_color: #222
  }
}

or

config = skeu-config('gray')

preset types in 'gray' | 'pink' | 'purple' | 'yellow' | 'green' | 'blue' | 'red'.

2. edit main.styl as following.

   @import 'stylus-skeuomorphic'
   
   // config as the previous section.
   //
   // config = ...
   
   stylus-skeuomorphic(config)
   
   isolate-all = skeu-gray.isolate-all
   .my-class
     { isolate-all }
   
   // this meaning is same as following...
   // isolate-normal = skeu-gray.isolate.normal
   // isolate-hover  = skeu-gray.isolate.hover
   // isolate-active = skeu-gray.isolate.active
   // .my-class
   //   { isolate-normal }
   //   &:hover
   //     { isolate-hover }
   //   &:active
   //     { isolate-active }
   
   // more styles...
   .my-class
     size 200px 50px
     text-align center
     font 'sans-serif'

Compile

compile main.styl file.

$(npm bin)/stylus -u stylus-skeuomorphic main.styl
# if stylus installed with global
stylus -u stylus-skeuomorphic main.styl

Draw normal state

• isolate-normal = skeu-{name}.isolate.normal

• chain-normal = skeu-{name}.chain.normal as chainable both sides.

• chain-left-normal = skeu-{name}.chain-left.normal as chinable only left side.

• chain-right-normal = skeu-{name}.chain-right.normal as chinable only right side.

Draw hover state

• isolate-hover = skeu-{name}.isolate.hover

• chain-hover = skeu-{name}.chain.hover as chinable both sides.

• chain-left-hover = skeu-{name}.chain-left.hover as chinable only left side.

• chain-right-hover = skeu-{name}.chain-right.hover as chinable only right side.

Draw active state

• isolate-active = skeu-{name}.isolate.active chain-active = skeu-{name}.chain.active chain-left-active = skeu-{name}.chain-left.active chain-right-active = skeu-{name}.chain-right.active

Config

name

define variable as skeu-{name} in global.

preset = skeu-config('pink')

.my-class
  { isolate-all }

material

stylus-skeuomorphic(config)

normal, hover, active

preset = skeu-config('pink')

import theme

making theme in JSON format as following.

{
  "name": "'blue'",
  "material": {
    "duration": "100ms",
    "texture": {
      "type": "'tl_stripe'",
      "times": 9,
      "opacity": 0.2
    },
    "bg_color": "#33aadd",
    "vignette_effect": 0.3,
    "diffusion": 0,
    "top": {
      "blend": 0.18,
      "alpha": 0.8
    },
    "bottom": {
      "blend": 0.18,
      "alpha": 0.5
    }
  },
  "normal": {
    "theme_color": "#33aadd",
    "lightness_mod": -48,
    "saturation_mod": -60,
    "spin_mod": "0deg",
    "txt_color": "#c33"
  },
  "hover": {
    "theme_color": "#33aadd",
    "lightness_mod": -48,
    "saturation_mod": -60,
    "spin_mod": "0deg",
    "txt_color": "#f33"
  },
  "active": {
    "theme_color": "#33aadd",
    "lightness_mod": -48,
    "saturation_mod": -60,
    "spin_mod": "0deg",
    "txt_color": "#077"
  }
}

and use json() function.

config = json('path/to/theme/blue.json', { hash: true })
