|
| +The `x-style` extension of the native `<style>` element allows defining styles
|
| +in the main document that can take advantage of several special features of
|
| +Polymer's styling system:
|
| +
|
| +* Document styles defined in an `x-style` will be shimmed to ensure they do
|
| +not leak into local DOM when running on browsers without non-native Shadow DOM.
|
| +* Shadow DOM-specific `/deep/` and `::shadow` combinators will be shimmed on
|
| +browsers without non-native Shadow DOM.
|
| +* Custom properties used by Polymer's experimental shim for cross-scope styling
|
| +may be defined in an `x-style`.
|
| +
|
| +Example:
|
| +
|
| +```html
|
| +<!doctype html>
|
| +<html>
|
| +<head>
|
| + <script src="components/webcomponentsjs/webcomponents-lite.js"></script>
|
| + <link rel="import" href="components/polymer/polymer.html">
|
| +
|
| + <style is="x-style">
|
| +
|
| + /* Will be prevented from affecting local DOM of Polymer elements */
|
| + * {
|
| + box-sizing: border-box;
|
| + }
|
| +
|
| + /* Can use /deep/ and ::shadow combinators */
|
| + body /deep/ .my-special-view::shadow #thing-inside {
|
| + background: yellow;
|
| + }
|
| +
|
| + /* Custom properties that inherit down the document tree may be defined */
|
| + body {
|
| + --my-toolbar-title-color: green;
|
| + }
|
| +
|
| + </style>
|
| +
|
| +</head>
|
| +<body>
|
| +
|
| + ...
|
| +
|
| +</body>
|
| +</html>
|
| +```
|
| +
|
| +Note, all features of `x-style` are available when defining styles as part of Polymer elements (e.g. `<style>` elements within `<dom-module>`'s used for defining Polymer elements. The `x-style` extension should only be used for defining document styles, outside of a custom element's local DOM.
