A polymer element to display "star" ratings in a paper style
First you need bower, see their site for details
bower install --save l2t-paper-rating
<l2t-paper-rating></l2t-paper-rating> <br/>
<l2t-paper-rating rating="2" readonly></l2t-paper-rating> <br/>
<l2t-paper-rating rating="3" total="4"></l2t-paper-rating>For screen readers it's helpful to have a label though the traditional label element will not work with custom elements so we'll need to change the aria-label or aria-labelledby properties directly.
There are examples of both methods on the demo page.
The following custom properties are available for styling:
| Custom property | Description | Default |
|---|---|---|
| --rating-icon-color | The color of the icons | --primary-text-color |
| --rating-icon-size | The size of the icon (square) | 28px |
| --rating-icon-padding | The size of the padding between icons | 2px |
| --rating-ink-color | The color of the ripple on icon tap | --primary-text-color |
| --rating-unselected-opacity | The opacity of stars 'non-active' | 0.4 |
| Attribute Name | Functionality | Type | Default |
