CSSClient Methods

Inserts a new rule with the given `ruleText` in a stylesheet with given `styleSheetId`, at the position specified by `location`.

Returns all class names from specified stylesheet.

Creates a new special "via-inspector" stylesheet in the frame with given `frameId`.

Disables the CSS agent for the given page.

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.

Determines whether the specified object is equal to the current object.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Ensures that the given node will have specified pseudo-classes whenever its style is computed by the browser.

GetBackgroundColors

Returns the computed style for a DOM node identified by `nodeId`.

Serves as the default hash function.

Returns the styles defined inline (explicitly in the "style" attribute and implicitly, using DOM attributes) for a DOM node identified by `nodeId`.

Returns all layers parsed by the rendering engine for the tree scope of a node. Given a DOM element identified by nodeId, getLayersForNode returns the root layer for the nearest ancestor document or shadow root. The layer root contains the full layer tree for the tree scope and their ordering.

Returns requested styles for a DOM node identified by `nodeId`.

Returns all media queries parsed by the rendering engine.

Requests information about platform fonts which we used to render child TextNodes in the given node.

Returns the current textual content for a stylesheet.

Gets the Type of the current instance.

Creates a shallow copy of the current Object.

Stop tracking rule usage and return the list of rules that were used since last call to `takeCoverageDelta` (or since start of coverage instrumentation)

Obtain list of rules that became used since last call to this method (or since start of coverage instrumentation)

Returns a string that represents the current object.

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.
