A CSS rule-set consists of a selector and a declaration. The selector specifies which element(s) to style, and the declaration contains the property and the value which define how the element will be styled. Variables are not part of a CSS rule-set.

The best approach to locate the Cancel button in a specific dialog is to add a unique class name to the button and use it to locate the button within the loaded dialog. This approach is more reliable than using absolute XPath, which can become invalid if the structure of the page changes, or link text, which may not be unique. Additionally, using a unique class name allows you to reuse the button in multiple dialogs and makes your code more maintainable.
