Overview
Vendored Google Closure Library module providing the SafeStyleSheet type and its builders for safe CSS style sheet handling, used by Selenium JavaScript atoms.
Description
goog.html.SafeStyleSheet is a vendored copy of the Google Closure Library module. It provides a string-like object representing a CSS style sheet that carries the security type contract that its value will not cause untrusted script execution (XSS) when evaluated as CSS in a browser. Instances must be created via the factory method SafeStyleSheet.fromConstant and are composable. The type ensures that values can be safely interpolated as the content of a style element within HTML. Selenium uses this as part of its JavaScript atom infrastructure for browser automation commands.
Usage
This module is consumed internally by Selenium's JavaScript atoms build system. It is not imported directly by end users.
