Graphic elements contribute to the experience without being cluttered or confusing. Links to other pages and to internal resources all work as expected. The layout of most pages is clear and easy to follow, and follows a consistent design theme. Headers and fonts contribute to the overall understanding and flow of the information, and help to move the eye from main topics to supporting details. Headers and fonts are usually appropriately used.
Most pages follow the same or similar design theme.
Or pages have a different look and feel and it is not clear that they form part of an organized set to accomplish a goal. They work together to create a pleasant viewing experience. If present the contrast is inappropriate or the background is too busy, which makes the text hard to read. The site would have been better if they left out many of the graphics and icons.
