Introduction

Automate and standardize website content policies and ensure compliance to brand, legal, style, and regulatory standards.

CSS (Cascading Style Sheet) is a stylesheet language that is used to control the format and/or layout of web documents and pages.

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.

This article provides instructions on how to set up and use policies based on CSS selectors.
