Please review it carefully and let us know by email at

Your comment on Visual Presentation: Understanding Success Criterion 1.4.3:

Working Group Resolution (LC-2962):
Browser vendors do have some responsibility for how they render author
generated content by default. UAAG helps to indicate to user agent vendors
to them how to achieve this. The most relevant UAAG Guidelines and success
criteria are likely to come under Guideline 1.8 (See 1.8.8 Customize
Viewport Highlighting for example). [1] [2]

However, it is ultimately the responsibility of the author claiming WCAG
conformance to ensure that the success criteria have been met. When user
agents conform to UAAG 2.0, many of the success criteria, such as this one,
are met automatically and the author does not need to take specific action.
When user agents do not meet this automatically, authors must take specific
action in the content. This varies according to the accessibility support
of the user agents expected to be used by the audience.
