Navigating the website with the keyboard
This website allows users to navigate using only the keyboard. You can navigate the website by pressing the "Tab" key, which is most often located on the left side of the keyboard. Each press of the key moves the cursor to the next element on the page, such as links to other pages or buttons relevant to the page. Pressing the "Shift" and "Tab" keys simultaneously moves the cursor to the previous element. The focused element is highlighted by changing color and looks like a framed box. To activate this element (i.e. "click on it"), press the "Enter" key.
The first element that is available when navigating with the keyboard is a shortcut to the main content of the page - you can use this to skip the navigation elements and get to the content of each page immediately, which is especially convenient for screen reader users.
Font size
There are three main ways to zoom in on a website:
1. Font (text) sizes built into the website
This website has three different font (text) sizes built into it, which you can choose by checking them here or in the upper right corner of the website in the “Accessibility” section. When you select one of the font sizes, all content on the website is enlarged to the corresponding size.
To turn off zooming, click the “Restore” button in the “Accessibility” section.
2. Built-in browser features
All popular browsers allow you to zoom in and out, or reduce the displayed content. To zoom in, press the “Ctrl” and “+” keys on your keyboard at the same time, to zoom out, press the “Ctrl” and “-” keys. Alternatively, hold down the “Ctrl” key and scroll up or down with the mouse wheel.
3. Built-in features of the operating system
Windows 10 and Windows 7 have a magnifier - a program that allows you to zoom in. Click the “Start” menu and type “Magnifier” ("Start" > "Magnifier") and press the Enter key. A small overlay window appears that you can move with the mouse and zoom in on all the content in it at different distances.
On Apple computers, go to the “Apple” menu > System Preferences > Accessibility (or Universal Access) > “Zoom”.
On Windows XP, go to “Start” > All Programs > Accessories > Accessibility > Magnifier.
Contrast Change
This website allows users to achieve higher text contrast by changing the colors of the content. The contrast of the website can be changed in three different combinations:
1. white text on a black background,
2. black text on a yellow background,
3. yellow text on a black background.
To change the contrast, you can select the desired one here or in the upper right corner of the website under the “Accessibility” section.
To turn off the contrast mode, click the “Restore” button under the “Accessibility” section.
Using a screen reader
A screen reader is software that attempts to detect and interpret what is displayed on the screen. This interpretation is then repeated to the user in audio form or through a Braille display.
The content of this website has been created in accordance with the technical standards for screen readers. For example, images have “alt” text (a textual description of the image’s content), while buttons, content, and other practical page elements are positioned and organized so that the sequence of information read by a screen reader is logical and easy to follow.
