class CSSDomain
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.
addRule |
Inserts a new rule with the given suspend fun addRule(input: AddRuleRequest): AddRuleResponse |
collectClassNames |

disable |
Disables the CSS agent for the given page. suspend fun disable(): Unit |
enable |
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. suspend fun enable(): Unit |
events |
Subscribes to all events related to this domain. fun events(): Flow<CSSEvent> |
fontsUpdated |
Fires whenever a web font is updated. A non-empty font parameter indicates a successfully loaded web font fun fontsUpdated(): Flow<FontsUpdatedEvent> |
forcePseudoState |
Ensures that the given node will have specified pseudo-classes whenever its style is computed by the browser. suspend fun forcePseudoState(input: ForcePseudoStateRequest): Unit |
getBackgroundColors |
suspend fun getBackgroundColors(input: GetBackgroundColorsRequest): GetBackgroundColorsResponse |
getComputedStyleForNode |
Returns the computed style for a DOM node identified by suspend fun getComputedStyleForNode(input: GetComputedStyleForNodeRequest): GetComputedStyleForNodeResponse |
getInlineStylesForNode |
Returns the styles defined inline (explicitly in the "style" attribute and implicitly, using
DOM
attributes) for a DOM node identified by suspend fun getInlineStylesForNode(input: GetInlineStylesForNodeRequest): GetInlineStylesForNodeResponse |
getMatchedStylesForNode |
Returns requested styles for a DOM node identified by suspend fun getMatchedStylesForNode(input: GetMatchedStylesForNodeRequest): GetMatchedStylesForNodeResponse |
getMediaQueries |
Returns all media queries parsed by the rendering engine. suspend fun getMediaQueries(): GetMediaQueriesResponse |
getPlatformFontsForNode |
Requests information about platform fonts which we used to render child TextNodes in the given node. suspend fun getPlatformFontsForNode(input: GetPlatformFontsForNodeRequest): GetPlatformFontsForNodeResponse |
getStyleSheetText |
Returns the current textual content for a stylesheet. suspend fun getStyleSheetText(input: GetStyleSheetTextRequest): GetStyleSheetTextResponse |
mediaQueryResultChanged |
Fires whenever a MediaQuery result changes (for example, after a browser window has been resized.) The current implementation considers only viewport-dependent media features. fun mediaQueryResultChanged(): Flow<MediaQueryResultChangedEvent> |
setEffectivePropertyValueForNode |
Find a rule with the given active property for the given node and set the new value for this property suspend fun setEffectivePropertyValueForNode(input: SetEffectivePropertyValueForNodeRequest): Unit |
setKeyframeKey |
Modifies the keyframe rule key text. suspend fun setKeyframeKey(input: SetKeyframeKeyRequest): SetKeyframeKeyResponse |
setLocalFontsEnabled |
Enables/disables rendering of local CSS fonts (enabled by default). suspend fun setLocalFontsEnabled(input: SetLocalFontsEnabledRequest): Unit |
setMediaText |
Modifies the rule selector. suspend fun setMediaText(input: SetMediaTextRequest): SetMediaTextResponse |
setRuleSelector |
Modifies the rule selector. suspend fun setRuleSelector(input: SetRuleSelectorRequest): SetRuleSelectorResponse |
setStyleSheetText |
Sets the new stylesheet text. suspend fun setStyleSheetText(input: SetStyleSheetTextRequest): SetStyleSheetTextResponse |
setStyleTexts |
Applies specified style edits one after another in the given order. suspend fun setStyleTexts(input: SetStyleTextsRequest): SetStyleTextsResponse |
startRuleUsageTracking |
Enables the selector recording. suspend fun startRuleUsageTracking(): Unit |
stopRuleUsageTracking |
Stop tracking rule usage and return the list of rules that were used since last call to
suspend fun stopRuleUsageTracking(): StopRuleUsageTrackingResponse |
styleSheetAdded |
Fired whenever an active document stylesheet is added. fun styleSheetAdded(): Flow<StyleSheetAddedEvent> |
styleSheetChanged |
Fired whenever a stylesheet is changed as a result of the client operation. fun styleSheetChanged(): Flow<StyleSheetChangedEvent> |
styleSheetRemoved |
Fired whenever an active document stylesheet is removed. fun styleSheetRemoved(): Flow<StyleSheetRemovedEvent> |
takeComputedStyleUpdates |
Polls the next batch of computed style updates. suspend fun takeComputedStyleUpdates(): TakeComputedStyleUpdatesResponse |
takeCoverageDelta |
Obtain list of rules that became used since last call to this method (or since start of coverage instrumentation) suspend fun takeCoverageDelta(): TakeCoverageDeltaResponse |
trackComputedStyleUpdates |
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. suspend fun trackComputedStyleUpdates(input: TrackComputedStyleUpdatesRequest): Unit |
