How deeply does CSS in Depth, Second Edition cover author style?

Explains stylesheet origins and practical overrides, but stops short of detailed cascade conflict resolution.

Author style

As explained in CSS in Depth, Second Edition

A stylesheet supplied by the document or application author whose declarations participate in the CSS cascade.

Author styles are declarations supplied by a web page or application. They form one stylesheet origin alongside user styles and user-agent styles, and they normally override browser defaults. section 1.1.1

Browser defaults provide familiar margins, list bullets, link colors, and font sizes. Author styles replace those defaults when the rendered design requires different values; multiple linked stylesheets still share the author origin. section 1.1.1

Replacing navigation defaults

A navigation rule can remove list padding and bullets, display items inline, and restyle links with a colored background, padding, rounded corners, and no underline.

Use revert when author declarations should be undone while browser defaults return. Applying it selectively to text-decoration restores the default underline without changing the gray link color. section 1.3.4
