We firmly believe that the Internet should be accessible to everyone, and we are committed to providing a website that is accessible to as many people as possible, regardless of their circumstances or abilities.
To this end, we strive to comply as closely as possible with the World Wide Web Consortium (W3C) Web Content Accessibility Guidelines (WCAG 2.1) at Level AA. These guidelines explain how to make web content accessible to people with various disabilities. Adhering to these guidelines helps us ensure that the website is accessible to everyone: people who are blind, people with mobility impairments, visual impairments, cognitive disabilities, and so on.
This website uses various technologies designed to make it as accessible as possible at all times. We use an accessibility interface that allows people with specific disabilities to adjust the website’s user interface (UI) and customize it to suit their personal needs.
In addition, the website uses an AI-powered application that runs in the background and continuously optimizes its accessibility. This application corrects the website’s HTML code and adapts its features and behavior to accommodate screen readers used by blind users and keyboard functions used by people with motor disabilities.
If you have noticed a problem or have suggestions for improvement, please don’t hesitate to let us know. You can contact the website administrators at the following email address: secretariat@ljbm.lu.
Our website uses ARIA (Accessible Rich Internet Applications) attributes, as well as various behavioral adjustments, to ensure that blind users who visit the site using screen readers can read, understand, and take full advantage of the site’s features. As soon as a user with a screen reader accesses your site, they immediately receive a prompt asking them to enter their screen reader profile so they can navigate and use your site effectively. Here’s how our website meets some of the most important screen reader requirements, accompanied by console screenshots with code examples:
Screen reader optimization: We run a background process that maps out the website’s components from top to bottom to ensure ongoing compliance even as the website is updated. As part of this process, we provide screen readers with meaningful data using the ARIA attribute set. For example, we provide precise form labels, descriptions for actionable icons (social media icons, search icons, shopping cart icons, etc.), validation hints for form inputs, and roles for elements such as buttons, menus, modal dialog boxes (pop-ups), and others. Additionally, the background process analyzes all images on the website and provides an accurate and meaningful description based on object recognition within the images, in the form of an ALT tag (alternative text) for images that are not described. It also extracts text embedded within the image using OCR (optical character recognition) technology. To activate screen reader settings at any time, users simply need to press the Alt+1 key combination. Screen reader users also receive automatic prompts to activate screen reader mode as soon as they access the website.
These settings are compatible with all common screen readers, including JAWS and NVDA.
Optimizing keyboard navigation: The background process also adjusts the website’s HTML code and adds various behaviors using JavaScript to make the website accessible via keyboard. This includes the ability to navigate the website using the Tab and Shift+Tab keys, use dropdown menus with the arrow keys, close them using the Esc key, activate buttons and links using the Enter key, navigate between radio buttons and checkboxes using the arrow keys, and filling them in using the Spacebar or the Enter key. Additionally, keyboard users will find quick navigation and content skip menus, available at any time by pressing Alt+1, or as the first elements on the site when navigating with the keyboard. The background process also handles pop-up windows by shifting keyboard focus to them as soon as they appear and preventing focus from moving away from them.
Users can also use shortcuts such as "M" (menus), "H" (headings), "F" (forms), "B" (buttons), and "G" (graphics) to access specific elements.
We strive to support as many browsers and assistive technologies as possible so that our users can choose the tools that work best for them, with as few restrictions as possible. That is why we have worked hard to support all major systems that account for over 95% of the market share, including Google Chrome, Mozilla Firefox, Apple Safari, Opera, and Microsoft Edge, as well as JAWS and NVDA (screen readers).
Despite our best efforts to ensure that everyone can adapt the website to their needs, some pages or sections may not yet be fully accessible, may be in the process of being made accessible, or may lack the appropriate technological solution to make them accessible. Nevertheless, we are continuously improving our accessibility by adding, updating, and enhancing its options and features, and by developing and adopting new technologies. All of this is done with the goal of achieving optimal accessibility, keeping pace with technological advancements. For assistance, please contact secretariat@ljbm.lu.
