- * The observedSet abstraction is a perf optimization which reduces the total
- * number of Object.observe observations of a set of objects. The idea is that
- * groups of Observers will have some object dependencies in common and this
- * observed set ensures that each object in the transitive closure of
- * dependencies is only observed once. The observedSet acts as a write barrier
- * such that whenever any change comes through, all Observers are checked for
- * changed values.
- *
- * Note that this optimization is explicitly moving work from setup-time to
- * change-time.
- *
- * TODO(rafaelw): Implement "garbage collection". In order to move work off
- * the critical path, when Observers are closed, their observed objects are
- * not Object.unobserve(d). As a result, it's possible that if the observedSet
- * is kept open, but some Observers have been closed, it could cause "leaks"
- * (prevent otherwise collectable objects from being collected). At some
- * point, we should implement incremental "gc" which keeps a list of
- * observedSets which may need clean-up and does small amounts of cleanup on a
- * timeout until all is clean.

- 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 Platform.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.
