The goal is to allow users to avoid the \n most obvious pitfalls and do so without compromi sing performance significantly. \n For ShadowDOM styling that's not covered her e, a set of best practices\n can be provided that should allow users to accompl ish more complex styling.\n\n The following is a list of specific ShadowDOM sty ling features and a brief\n discussion of the approach used to shim.\n\n Shimm ed features:\n\n * :host, :host-context: ShadowDOM allows styling of the shadow Root's host\n element using the :host rule. To shim this feature, the :host sty les are \n reformatted and prefixed with a given scope name and promoted to a \ n document level stylesheet.\n For example, given a scope name of .foo, a rule like this:\n \n :host {\n background: red;\n }\n }\n \n be comes:\n \n .foo {\n background: red;\n }\n \n * encapsultion: Sty les defined within ShadowDOM, apply only to \n dom inside the ShadowDOM. Polyme r uses one of two techniques to imlement\n this feature.\n \n By default, rul es are prefixed with the host element tag name \n as a descendant selector. Thi s ensures styling does not leak out of the 'top'\n of the element's ShadowDOM. For example,\n\n div {\n font-weight: bold;\n }\n \n becomes:\n\n x- foo div {\n font-weight: bold;\n }\n \n becomes:\n\n\n Alternatively, if Platform.ShadowCSS.strictStyling is set to true then \n selectors are scope d by adding an attribute selector suffix to each\n simple selector that contain s the host element tag name. Each element \n in the element's ShadowDOM templat e is also given the scope attribute. \n Thus, these rules match only elements t hat have the scope attribute.\n For example, given a scope name of x-foo, a rul e like this:\n \n div {\n font-weight: bold;\n }\n \n becomes:\n \n div[x-foo] {\n font-weight: bold;\n }\n\n Note that elements that are dynamically added to a scope must have the scope\n selector added to them manually.\n\n * upper/lower bound encapsulation: Styles which are defined outsi de a\n shadowRoot should not cross the ShadowDOM boundary and should not apply\ n inside a shadowRoot.\n\n This styling behavior is not emulated. Some possibl e ways to do this that \n were rejected due to complexity and/or performance co ncerns include: (1) reset\n every possible property for every possible selector for a given scope name;\n (2) re-implement css in javascript.\n \n As an alt ernative, users should make sure to use selectors\n specific to the scope in wh ich they are working.\n \n * ::distributed: This behavior is not emulated. It' s often not necessary\n to style the contents of a specific insertion point and instead, descendants\n of the host element can be styled selectively. Users ca n also create an \n extra node around an insertion point and style that node's contents\n via descendent selectors. For example, with a shadowRoot like this:\ n \n <style>\n ::content(div) {\n background: red;\n }\n </style>\n <content></content>\n \n could become:\n \n <style>\n / *@polyfill .content-container div * / \n ::content(div) {\n backgr ound: red;\n }\n </style>\n <div class=\"content-container\">\n <content></content>\n </div>\n \n Note the use of @polyfill in the comment above a ShadowDOM specific style\n declaration. This is a directive to the styl ing shim to use the selector \n in comments in lieu of the next selector when r unning under polyfill.\n*/\n(function(scope) {\n\nvar ShadowCSS = {\n strictSty ling: false,\n registry: {},\n // Shim styles for a given root associated with a name and extendsName\n // 1. cache root styles by name\n // 2. optionally t ag root nodes with scope name\n // 3. shim polyfill directives /* @polyfill */ and /* @polyfill-rule */\n // 4. shim :host and scoping\n shimStyling: functio n(root, name, extendsName) {\n var scopeStyles = this.prepareRoot(root, name, extendsName);\n var typeExtension = this.isTypeExtension(extendsName);\n var scopeSelector = this.makeScopeSelector(name, typeExtension);\n // use cac hing to make working with styles nodes easier and to facilitate\n // lookup o f extendee\n var cssText = stylesToCssText(scopeStyles, true);\n cssText = this.scopeCssText(cssText, scopeSelector);\n // cache shimmed css on root fo r user extensibility\n if (root) {\n root.shimmedStyle = cssText;\n } \n // add style to document\n this.addCssToDocument(cssText, name);\n },\ n /*\n * Shim a style element with the given selector.

The goal is to allow users to avoid the \n most obvious pitfalls and do so without compromi sing performance significantly. \n For ShadowDOM styling that's not covered her e, a set of best practices\n can be provided that should allow users to accompl ish more complex styling.\n\n The following is a list of specific ShadowDOM sty ling features and a brief\n discussion of the approach used to shim.\n\n Shimm ed features:\n\n * :host, :host-context: ShadowDOM allows styling of the shadow Root's host\n element using the :host rule. To shim this feature, the :host sty les are \n reformatted and prefixed with a given scope name and promoted to a \ n document level stylesheet.\n For example, given a scope name of .foo, a rule like this:\n \n :host {\n background: red;\n }\n }\n \n be comes:\n \n .foo {\n background: red;\n }\n \n * encapsultion: Sty les defined within ShadowDOM, apply only to \n dom inside the ShadowDOM. Polyme r uses one of two techniques to imlement\n this feature.\n \n By default, rul es are prefixed with the host element tag name \n as a descendant selector. Thi s ensures styling does not leak out of the 'top'\n of the element's ShadowDOM. For example,\n\n div {\n font-weight: bold;\n }\n \n becomes:\n\n x- foo div {\n font-weight: bold;\n }\n \n becomes:\n\n\n Alternatively, if Platform.ShadowCSS.strictStyling is set to true then \n selectors are scope d by adding an attribute selector suffix to each\n simple selector that contain s the host element tag name. Each element \n in the element's ShadowDOM templat e is also given the scope attribute. \n Thus, these rules match only elements t hat have the scope attribute.\n For example, given a scope name of x-foo, a rul e like this:\n \n div {\n font-weight: bold;\n }\n \n becomes:\n \n div[x-foo] {\n font-weight: bold;\n }\n\n Note that elements that are dynamically added to a scope must have the scope\n selector added to them manually.\n\n * upper/lower bound encapsulation: Styles which are defined outsi de a\n shadowRoot should not cross the ShadowDOM boundary and should not apply\ n inside a shadowRoot.\n\n This styling behavior is not emulated. Some possibl e ways to do this that \n were rejected due to complexity and/or performance co ncerns include: (1) reset\n every possible property for every possible selector for a given scope name;\n (2) re-implement css in javascript.\n \n As an alt ernative, users should make sure to use selectors\n specific to the scope in wh ich they are working.\n \n * ::distributed: This behavior is not emulated. It' s often not necessary\n to style the contents of a specific insertion point and instead, descendants\n of the host element can be styled selectively. Users ca n also create an \n extra node around an insertion point and style that node's contents\n via descendent selectors. For example, with a shadowRoot like this:\ n \n <style>\n ::content(div) {\n background: red;\n }\n </style>\n <content></content>\n \n could become:\n \n <style>\n / *@polyfill .content-container div * / \n ::content(div) {\n backgr ound: red;\n }\n </style>\n <div class=\"content-container\">\n <content></content>\n </div>\n \n Note the use of @polyfill in the comment above a ShadowDOM specific style\n declaration.
