Overview

Package domsnapshot provides Go bindings for the `DOMSnapshot` domain (https://chromedevtools.github.io/devtools-protocol/tot/DOMSnapshot) in the Chrome DevTools Protocol (CDP), version 1.3.

This domain facilitates obtaining document snapshots with DOM, layout, and style information.

This domain is experimental!

	// that overlap with the current element.
	//
	// This CDP parameter is experimental.
	IncludeBlendedBackgroundColors bool `json:"includeBlendedBackgroundColors,omitempty"`
	// Whether to include text color opacity in the snapshot (default: false).

CaptureSnapshot contains the parameters, and acts as a Go receiver, for the CDP command `captureSnapshot`.

Returns a document snapshot, including the full DOM tree of the root node (including iframes, template contents, and imported documents) in a flattened array, as well as layout and white-listed computed style information for the nodes. Shadow DOM in the returned DOM tree is flattened.
