This website has been constructed and compiled to comply with WCAG 2.0 AA accessibility guidelines. This means that certain technical tools and content compilation principles have been used that help users with visual or hearing disabilities to consume the content of the website.
In addition, accessibility of the information can be enhanced by adjusting the browser and operating system settings of your computer. Below is a survey of the main assistive tools.
Navigating by keyboard
It is possible to navigate the website by keyboard alone. “Tab” key is used for navigation. Each press moves the focus to the next element. The currently active element is marked by a box surrounding it. To activate a link in focus, press the “Enter“ key on the keyboard.
Enlarging the content
To enlarge the content, we first recommend to use the functionality built in to the web browser.
In all popular web browsers, it is possible to zoom in and out of the page by holding down Ctrl (Cmd in OS X operating system) and at the same time pressing either + or –. Another convenient option is to use the mouse: hold down Ctrl and at the same time roll the mouse wheel. To restore the normal size, press Ctrl and 0 simultaneously.
All common operating systems contain settings for enlarging the content displayed on the screen.
- In Windows 7, you will find the program “Magnifier” when you press the “Start” menu button down on the left, type “Magnifier” (a few initial letters will be enough) and press Enter. A small window opens, displaying the content enlarged. By default, the program follows the position of the mouse cursor.
- In Windows XP, you will find the program “Magnifier” by navigating Start > All Programs > Accessories > Accessibility > Magnifier.
- In Apple computers, the navigation path to use zoom is the following: Apple menu > System Preferences > Accessibility (or Universal Access) > Zoom.
Web browser extensions
For web browsers, there are zoom extensions that complement the existing functionality of the web browser.
- For example, Firefox has “Zoom Page”, that allows to zoom into the whole page or only the text;
- Chrome has “AutoZoom“.
Using the screen reader
Screen reader is a program for interpreting the content displayed on the screen and conveying it in other forms, e.g. sounds or audio comments. It is mainly an assistive tool for the visually impaired.
