Not all visually impaired people make use of technical support to navigate on the internet. The feature to increase fonts is an important element to ensure that all information of the website can be read by all users. Even people who are not visually impaired need to increase the font sometimes. At the same time, an increasing number of older people surf the web; they too need a feature to increase the font. To this purpose, it is important to define the font size not in pixel, but in percentage or "em".

Some font size (less than 5%) are fixed and cannot be increased, or a less ideal feature using Javascript is being used.

"Even though machine-level addressing like the URL should never have been exposed in the user interface, it is there and we have found that users actually try to decode the URLs of pages to infer the structure of web sites. Users do this because of the horrifying lack of support for navigation and sense of location in current web browsers. Thus, a URL should contain human-readable directory and file names that reflect the nature of the information space."

The URL structure of the tested Website is generally good, though some complex URLs are used internally.
When clicking on a link, web users expect to see the new page in the existing window. Most users lose control if there are several windows open, are unable to navigate back with the back function and get lost. At the same time, and this is particularly true for old computers, the system can get overloaded and crash if too many browser windows open. If new windows open but are not seen by the user, the perception is that the website does not work properly. Experienced users who want to open new windows know how to do this by using the function "Open (link) in New Window", or with similar comands.
There is one important exception to this rule: files in .PDF or other Office format can be opened in new windows. Users know to close them to return to the original window. In this case, users should be informed that a new window opened, and they should be given the opportunity to save the file.
Technical hint: For XHTML Strict in particular, there is the possibility to send a .PDF file with ContentType "application/pdf" and HTTP Header content-disposition: attachment; filename=filename.pdf, since there is no target attribute. This test does not take it into account yet, but this is a feasible solution.

At least one internal hyperlink opening a new window was found.
Separating design and structure of the website carries great advantages. The sharper the distinction, the more independent the two areas are. A lack of such a distinction is also called a "spaghetti mark-up" or a "tag-soup" (from the term "HTML tag").
Nowadays it is easy to save colours, type fonts, design images and to a large extent even the layout of the website in CSS files (CSS = Cascading Style Sheet).

Hint for IT technicians: "Code" does not refer to javascript, but to HTML source.
The tested website contains a small amount of spaghetti mark-up in CSS format.
