Supplementary Lexicon of Ancient Greek

The project Aristarchus has planned and realized a new accessible version of the site in order to make the provided tools more usable also to people with disabilities.

Web accessibility means the possibility to benefit from available contents and services aside from psychophysical disabilities and from hardware and software supply.

For this purpose, the Web Content Accessibility Guidelines WCAG 1.0, of the project WAI – W3C, have been followed, in the attempt to achieve a conformance level Triple-A (WCAG 1.0 AAA).

Layout and characters
The layout has been recreated and adapted to the accessibility requirements, by use of the markup language XHTML 1.0 strict for page structure and style sheets CSS 2.0 in order to check the graphic aspect. No table has been used to page up and all elements have been produced throught the most suitable tag XHTML.
Dimensions of characters and sections are percentage or relative unit of measure, so that it is possible to increase them (through browser tools) according to user’s needs. Distance between elements has been emphasized, in order to guarantee their separation, and the adopted character dimension are, as far as possible, not too small.
The choice of the colors tries to respect the WCAG 1.0 standard about foreground and background color combination: when pages are viewed by someone having color deficits or on a black and white screen, sufficient contrast must be provided. For this purpose it is necessary that difference in brightness and shade between foreground and background color exceed a given threshold value. W3C suggests an algorithm (subject to possible variations) to calculate this value: by applying the algorithm to all the combinations of color choosen for this site, results exceed a given threshold value.
Anyway, all information in the site is usable also without color.
Keyboard shortcuts
Keyboard shortcuts are provided for some links, specifically for the ones that connect the most important sections of the site. It is the letters in square brackets ([A, B, C...]) positioned just after the link to which they refer. They are useful to activate the link directly or to type in the data. These tools can be used following the instructions below:
