CSSClient Class

Version 88.2.90

This domain exposes CSS read/write operations. All CSS objects (stylesheets, rules, and styles) have an associated `id` used in subsequent operations on the related object. Each object type has a specific `id` structure, and those are not interchangeable between objects of different kinds. CSS objects can be loaded using the `get*ForNode()` calls (which accept a DOM node id). A client can also keep track of stylesheets via the `styleSheetAdded`/`styleSheetRemoved` events and subsequently load the required stylesheet contents using the `getStyleSheet[Text]()` methods.

Methods

	Name	Description
	AddRuleAsync	Inserts a new rule with the given `ruleText` in a stylesheet with given `styleSheetId`, at the position specified by `location`.
	CollectClassNamesAsync	Returns all class names from specified stylesheet.
	CreateStyleSheetAsync	Creates a new special "via-inspector" stylesheet in the frame with given `frameId`.
	DisableAsync	Disables the CSS agent for the given page.
	EnableAsync	Enables the CSS agent for the given page. Clients should not assume that the CSS agent has been enabled until the result of this command is received.
	EnumToString(Enum)	(Inherited from DevToolsDomainBase.)
	EnumToString(DisabledImageType)	(Inherited from DevToolsDomainBase.)
	EnumToString(PermissionType)	(Inherited from DevToolsDomainBase.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	ForcePseudoStateAsync	Ensures that the given node will have specified pseudo-classes whenever its style is computed by the browser.
	GetBackgroundColorsAsync	GetBackgroundColors
	GetComputedStyleForNodeAsync	Returns the computed style for a DOM node identified by `nodeId`.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetInlineStylesForNodeAsync	Returns the styles defined inline (explicitly in the "style" attribute and implicitly, using DOM attributes) for a DOM node identified by `nodeId`.
	GetMatchedStylesForNodeAsync	Returns requested styles for a DOM node identified by `nodeId`.
	GetMediaQueriesAsync	Returns all media queries parsed by the rendering engine.
	GetPlatformFontsForNodeAsync	Requests information about platform fonts which we used to render child TextNodes in the given node.
	GetStyleSheetTextAsync	Returns the current textual content for a stylesheet.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	SetEffectivePropertyValueForNodeAsync	Find a rule with the given active property for the given node and set the new value for this property
	SetKeyframeKeyAsync	Modifies the keyframe rule key text.
	SetLocalFontsEnabledAsync	Enables/disables rendering of local CSS fonts (enabled by default).
	SetMediaTextAsync	Modifies the rule selector.
	SetRuleSelectorAsync	Modifies the rule selector.
	SetStyleSheetTextAsync	Sets the new stylesheet text.
	SetStyleTextsAsync	Applies specified style edits one after another in the given order.
	StartRuleUsageTrackingAsync	Enables the selector recording.
	StopRuleUsageTrackingAsync	Stop tracking rule usage and return the list of rules that were used since last call to `takeCoverageDelta` (or since start of coverage instrumentation)
	TakeComputedStyleUpdatesAsync	Polls the next batch of computed style updates.
	TakeCoverageDeltaAsync	Obtain list of rules that became used since last call to this method (or since start of coverage instrumentation)
	ToBase64String	(Inherited from DevToolsDomainBase.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	TrackComputedStyleUpdatesAsync	Starts tracking the given computed styles for updates. The specified array of properties replaces the one previously specified. Pass empty array to disable tracking. Use takeComputedStyleUpdates to retrieve the list of nodes that had properties modified. The changes to computed style properties are only tracked for nodes pushed to the front-end by the DOM agent. If no changes to the tracked properties occur after the node has been pushed to the front-end, no updates will be issued for the node.
