ic-styled
Automatically style components with css templates.
Demo
http://instructure.github.io/ic-styled
Installation
bower install ic-styled
npm install ic-styled
... or download main.js and include it into your app however you want.
Module Support
ic-styled doesn't export anything, it just adds functionality to
Ember.Component. If using a module system, require it somewhere in the
root of your application somewhere (like application.js).
AMD
define(['ic-styled'], function() {});CJS
require('ic-styled')
Usage
Given a component named x-foo, create an additional component template
at components/x-foo-css, treat it like a css file. The css will be
imported into your app automatically on the first instance of x-foo.
Sounds tricky but its not; here's a sample app:
<script type="text/x-handlebars">
<h1>Application Template using x-foo</h1>
{{x-foo}}
</script>
<script type="text/x-handlebars" id="components/x-foo">
I am x-foo, the main component.
</script>
<script type="text/x-handlebars" id="components/x-foo-css">
/* I am x-foo-css, the styles that go with x-foo */
x-foo { color: red; font-weight: bold; }
</script>
<script>
var App = Ember.Application.create();
App.XFooComponent = Ember.Component.extend({
tagName: 'x-foo'
});
</script>At the first render of {{x-foo}} the {{x-foo-css}} template is
imported into the app to style x-foo elements.
Overriding Component Styles
Styled injects the css template to the top of the <head> element so
its the first-ish css to be applied. This means that you can override
the CSS of styled components the same as any native element since your
app's CSS will be applied after.
Vim Config
If you use vim, add this to your vimrc to get css highlighting for
these templates:
au BufNewFile,BufRead *-css.hbs set filetype=css
Use Tags to Style
I know, its been hammered into our brains not to use tagNames when
writing CSS. But, when you build a component, you are creating a new
custom element; you should mimick native elements as much as possible.
Therefore, style it by tagName so everybody consuming your component can
override styles the same way they override a <button>.
About the Implementation
A lot of questions come up, hopefully this answers them:
- all styles are injected into a shared
<style>tag to avoid the IE issue of only allowing 31 style/link tags - this style tag is at the top of the
<head>so application CSS can override the same way they override native element css - styles for a component definition are only injected once, even if the component is used several times
- a comment is inserted so you can see which component injected the css
