508 Compliance - SortSite level AA MMT and DraftMMT: Set colors on the BODY or A elements

[Francell]

Issue:
If you set any of the colors on the BODY or A elements you must set all of them.

Explanation:
In HTML the color attributes are TEXT, BGCOLOR, LINK, ALINK and VLINK. In CSS the attributes are COLOR and BACKGROUND-COLOR. Some users have browser defaults set to white text on a black background, so setting one color without setting the others can result in black text on a black background. High contrast mode on Windows turns off background images so you must set a background-color in addition to a background-image.

Guideline:
WCAG 1.0 AAA 2.2
WCAG 2.0 AA F24
