CSS Selectors are expressions that are used to target specific HTML elements to style on a website. Use CSS selectors to improve policy definition, limit searches, and/or exclude content in a policy efficiently. After they are set up, CSS selectors can be used to select elements. In other words, selectors are patterns that are used to select the element(s) to style.

Configure a new policy and specify certain CSS selectors, or patterns of elements, to flag. The browser searches for or excludes the CSS properties only within the targeted HTML elements.

Note: The Browser Extension does not yet support CSS selectors and therefore does not take any user-defined CSS selectors into consideration when highlighting matches.
