/*
|
||||
This is a limited shim for ShadowDOM css styling.
|
||||
https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html#styles
|
||||
|
||||
The intention here is to support only the styling features which can be
|
||||
relatively simply implemented. The goal is to allow users to avoid the
|
||||
most obvious pitfalls and do so without compromising performance significantly.
|
||||
For ShadowDOM styling that's not covered here, a set of best practices
|
||||
can be provided that should allow users to accomplish more complex styling.
|
||||
|
||||
The following is a list of specific ShadowDOM styling features and a brief
|
||||
discussion of the approach used to shim.
|
||||
|
||||
Shimmed features:
|
||||
|
||||
* :host, :host-context: ShadowDOM allows styling of the shadowRoot's host
|
||||
element using the :host rule. To shim this feature, the :host styles are
|
||||
reformatted and prefixed with a given scope name and promoted to a
|
||||
document level stylesheet.
|
||||
For example, given a scope name of .foo, a rule like this:
|
||||
|
||||
:host {
|
||||
background: red;
|
||||
}
|
||||
}
|
||||
|
||||
becomes:
|
||||
|
||||
.foo {
|
||||
background: red;
|
||||
}
|
||||
|
||||
* encapsultion: Styles defined within ShadowDOM, apply only to
|
||||
dom inside the ShadowDOM. Polymer uses one of two techniques to imlement
|
||||
this feature.
|
||||
|
||||
By default, rules are prefixed with the host element tag name
|
||||
as a descendant selector. This ensures styling does not leak out of the 'top'
|
||||
of the element's ShadowDOM. For example,
|
||||
|
||||
div {
|
||||
font-weight: bold;
|
||||
}
|
||||
|
||||
becomes:
|
||||
|
||||
x-foo div {
|
||||
font-weight: bold;
|
||||
}
|
||||
|
||||
becomes:
|
||||
|
||||
|
||||
Alternatively, if WebComponents.ShadowCSS.strictStyling is set to true then
|
||||
selectors are scoped by adding an attribute selector suffix to each
|
||||
simple selector that contains the host element tag name. Each element
|
||||
in the element's ShadowDOM template is also given the scope attribute.
|
||||
Thus, these rules match only elements that have the scope attribute.
|
||||
For example, given a scope name of x-foo, a rule like this:
|
||||
|
||||
div {
|
||||
font-weight: bold;
|
||||
}
|
||||
|
||||
becomes:
|
||||
|
||||
div[x-foo] {
|
||||
font-weight: bold;
|
||||
}
|
||||
|
||||
Note that elements that are dynamically added to a scope must have the scope
|
||||
selector added to them manually.
|
||||
|
||||
* upper/lower bound encapsulation: Styles which are defined outside a
|
||||
shadowRoot should not cross the ShadowDOM boundary and should not apply
|
||||
inside a shadowRoot.
|
||||
|
||||
This styling behavior is not emulated. Some possible ways to do this that
|
||||
were rejected due to complexity and/or performance concerns include: (1) reset
|
||||
every possible property for every possible selector for a given scope name;
|
||||
(2) re-implement css in javascript.
|
||||
|
||||
As an alternative, users should make sure to use selectors
|
||||
specific to the scope in which they are working.
|
||||
|

* ::distributed: This behavior is not emulated. It's often not necessary
|
||||
to style the contents of a specific insertion point and instead, descendants
|
||||
of the host element can be styled selectively. Users can also create an
|
||||
extra node around an insertion point and style that node's contents
|
||||
via descendent selectors. For example, with a shadowRoot like this:
|
||||
|
||||
<style>
|
||||
::content(div) {
|
||||
background: red;
|
||||
}
|
||||
</style>
|
||||
<content></content>
|
||||
|
||||
could become:
|
||||
|
||||
<style>
|
||||
/ *@polyfill .content-container div * /
|
||||
::content(div) {
|
||||
background: red;
|
||||
}
|
||||
</style>
|
||||
<div class="content-container">
|
||||
<content></content>
|
||||
</div>
|
||||
|
||||
Note the use of @polyfill in the comment above a ShadowDOM specific style
|
||||
declaration. This is a directive to the styling shim to use the selector
|
||||
in comments in lieu of the next selector when running under polyfill.
