    range: {
        min: 0,
        max: 100

Generating custom slider theme color

Ember slider provides a blueprint, using which you can change the look and feel (colors & size) of the slider within minutes. Run the blueprint with your preferred color values and the amount of scaling you need, it will give you the scss file with autogenerated code. To make use of the generator, you must have ember-cli-compass-compiler installed in your application.

ember g custom-slider <name_of_the_scss_file> <options>

Following are the options available.

  • --pathcolor - <type:string> Background color of the handle movement path
  • --fillerColor - <type:string> Background color of the region selected
  • --handleColor - <type:string> Background color of the handle
  • --classList - <type:string> CSS classname to be given to the generated slider
  • --scale - <type:number> Amount by which the entire slider needs to be scaled. Default is 1.
  1. To generate a red colored slider, you can do
ember g custom-slider red-slider --pathColor="#f5f5f5" --classList="red" --fillerColor="rgba(#ff6b43, .3)" --handleColor="#ff6b43"

The above command will generate a file called _red-slider.scss inside app/styles directory of your application.

  1. You can also generate 2 or more sliders at the same time.
ember g custom-slider all-sliders  --classList="red green" --pathColor="#f5f5f5 #f5f5f5" --fillerColor="rgba(#ff6b43, .3) rgba(#79c03b, .3)" --handleColor="#ff6b43 #79c03b" --scale="1 0.9"
