Setting "color" every time you set "background-color" (and vice versa), and setting "background-color" every time you set "background-image", is the only truly robust approach in the face of unpredictable markup and browser configurations. Also, make sure when you set :link colors you also set :unvisited too. You might find this less cumbersome if you generate your CSS with preprocessed templates, allowing you to define particular colors by name or function or even group whole declarations. Simple example using Perl: http://dorward.me.uk/www/css/inheritance/ Note also that "transparent" and "inherit" are valid "background-color" values, although the later is poorly supported by Internet Explorer 6. Good ways to test how such CSS works in practice include: 1. Change your default colors to white text on black. 2. Try one of Opera's High Contrast View options. 3. Try IE and Windows XP in "High Contrast" mode. 4. Disabling images. In terms of CSS and accessibility, note that Meyer's reset CSS, which you're using, unsets the default keyboard focus ring ("outline: 0;"), but you have not explicitly set any keyboard focus outline as a replacement. See http://www.w3.org/TR/WCAG20/#navigation-mechanisms-focus-visible for Web Accessibility Initiative's emerging guidance about ensuring keyboard focus is always visible.
