An Ember CLI addon which allows you to specify a component-specific style sheet inside of component pod directories
The announcement from EmberConf 2015
ember install ember-component-css
This addon allows you to specify a style sheet inside of your component's pod folder.
Rules defined in the style-sheet will automatically be namespaced with an autogenerated class. That autogenerated class will also be injected into your component's classNames
property. This enables you to worry less about rules clashing across component styles.
For example, given this app/my-component/styles.css
file:
& { // ampersand refers to the component itself (parent selector)
padding: 2px;
}
.urgent {
color: red;
}
Your generated CSS output will look something like:
.my-component-a34fba {
padding: 2px;
}
.my-component-a34fba .urgent {
color: red;
}
A typical component invocation that looks like this:
{{my-component}}
will generated markup like:
<div class="my-component-a34fba"></div>
To use this addon with a CSS pre-processor, import pod-styles
into your base stylesheet. (see your pre-processor docs)
// app/styles/app.scss
@import "pod-styles";
// app/styles/app.less
@import "pod-styles";
// app/styles/app.styl
@import 'pod-styles'
And that is it! The pod-styles
file is generated during the build and will then be pulled into your other stylesheet to be processed like normal.
Note: If you are using more then one type of component style files (ie a .less file and a .scss file) then you will need to add the extension to the @import. Otherwise the extension can be left off.
