Strefa57 - The best venue for concerts in Poland
We firmly believe that the internet should be accessible to everyone, and we do our utmost to ensure that our website is accessible to as wide an audience as possible, regardless of their circumstances or level of ability.
To achieve this, we endeavour to strictly adhere to the Web Content Accessibility Guidelines 2.1 (WCAG 2.1) at Level AA, as developed by the World Wide Web Consortium (W3C). These guidelines explain how to make web content accessible to people with various disabilities. Compliance with these guidelines helps to ensure that the website is accessible to everyone: people who are blind, have mobility impairments, visual impairments, cognitive disabilities and other disabilities.
This website uses a range of technologies designed to ensure the highest possible level of accessibility at all times. We use an accessibility interface that allows people with specific disabilities to customise the website’s appearance and functions to suit their own needs.
In addition, the website uses an AI-based application that runs in the background and continuously optimises accessibility. This application modifies the HTML code and adapts the website’s functionality and behaviour to the needs of users of screen readers and to enable keyboard navigation for people with limited mobility.
If you’ve come across an error or have an idea for an improvement, we’d love to hear from you. You can contact the website administrator via email at: info@strefa57.com
Our website uses ARIA (Accessible Rich Internet Applications) and various behavioural adjustments to ensure that blind users of screen readers can read, understand and use the website’s features. When a user with a screen reader visits the website, they are immediately prompted to switch to Screen Reader mode, which allows them to navigate the site effectively. Below, we outline how our website meets the key requirements for screen readers, along with examples of the code:
Optimisation for screen readers: We run a background process that analyses the page structure and ensures compliance even whilst the page is being updated. As part of this process, we provide screen readers with the relevant information using ARIA attributes. For example, we add labels to forms, descriptions of icons (e.g. social media, search, shopping basket), validation messages for forms, and element roles (buttons, menus, modal windows, etc.). This process also analyses all images and adds alternative descriptions generated on the basis of object recognition. OCR technology is also used to recognise text embedded within images. To activate screen reader mode at any time, press the Alt+1 key combination. Screen reader users also receive an automatic notification about the availability of this mode as soon as they visit the site.
These adjustments are compatible with all popular screen readers, including JAWS and NVDA.
Optimising keyboard navigation: A background process modifies the HTML and adds the necessary functionality via JavaScript, enabling the website to be navigated using only the keyboard. This includes navigation using the Tab and Shift+Tab keys, operating drop-down lists using the arrow keys, closing them with the Esc key, activating buttons and links using the Enter key, and operating checkboxes and radio buttons using the arrow keys and the space bar. Keyboard users also have access to the quick navigation menu (Alt+1) or via the first element on the page. Furthermore, in the case of pop-up windows, focus is automatically transferred to them to prevent it from being lost.
You can also use the following keyboard shortcuts: “M” (menu), “H” (headings), “F” (forms), “B” (buttons), “G” (graphics), to quickly jump to specific elements.
We strive to ensure the widest possible compatibility with all browsers and assistive technologies, so that users can make use of the tools best suited to their needs. That is why we support all major systems, covering over 95% of the market: Google Chrome, Mozilla Firefox, Apple Safari, Opera and Microsoft Edge, as well as the JAWS and NVDA screen readers.
Despite our best efforts, there may be pages or sections that are not yet fully accessible or are currently being improved. We are constantly working to improve accessibility by updating and implementing new features and technologies. All of this is aimed at achieving the highest possible level of accessibility in line with technological progress. If necessary, please contact us at info@strefa57.com
