Just 100 days left…

This article was written before 28 June 2025, when the legislation took effect. Its deadlines have passed; its advice has not.
Only 100 days remain until the European Accessibility Act takes effect – is approaching fast.
Don't panic…
First of all, check whether the European Accessibility Act (EAA) (external link) applies to you. But, very briefly: if you run an e-shop, a mobile application, or a website where you offer any kind of service, or if you send electronic invoices to end consumers, the EAA applies to you. If you're not sure, check with our test. B2B is not covered by the EAA, but if you offer a service that your partners then offer on to their own customers – end consumers – you're simply passing the problem on to them, and either you'll lose those partners, or they'll start passing the responsibility back to you. Take your pick of which is worse… If you also offer services or goods abroad, you'll need to check the local legislation too, since in some countries the EAA may have been implemented more strictly than it has been here.
Why does accessibility matter? Listen to the podcast Denník N (external link) recorded with us. We also most recently talked about accessibility for Basta Digital (external link).

What all needs to be accessible?
In short? Everything. But step by step. It's important to look at the whole spectrum of the service you provide and your communication with customers. Besides your website, mobile application, payment processes and so on, don't forget:
- published documents, especially contractual or business terms and other legally binding content,
- electronic invoices,
- instructions or manuals for the products and services you sell,
- accessible help and customer support,
- electronic communications such as newsletter emails or social media posts,
- promotional or informational videos and podcasts.
How do I check accessibility myself?
You don't need a PhD in information science (although we do have one :-)). To check basic accessibility, all you need to do is… put your mouse aside / turn off the touchpad. It takes some getting used to, but can you reach all the services and functions on your website using only the keyboard? Can you complete the checkout process without a mouse, or send a question through a chat bot? And does the way you move around the page without a mouse make logical sense? Congratulations – you've just checked two very important points: keyboard operability and a meaningful order.
It's only the beginning, but if you've passed this test, the rest will be easier. For example, the WAVE (external link) extension can help you quickly spot:
- contrast errors,
- missing text alternatives for images (unless they're purely decorative or illustrative graphics),
- missing labels for form fields,
- certain elements that can't be operated using the keyboard.
For more thorough testing, you can try Accessibility Insights (external link), which walks you through selected points from the WCAG (external link) guidelines (the Web Content Accessibility Guidelines – we also helped produce an unofficial Slovak translation (external link) of them). However, no automated tool checks more than 20–30% of the current requirements, and none of them can check accessibility against the EU's applicable standard, EN 301 549 (PDF, 2.2 MB) (external link). They won't verify whether the text alternatives used are accurate, whether users have sufficient instructions before and during form completion and are alerted to errors in a clear and accessible way, whether the reading order through the content is genuinely meaningful, and so on. Just as they miss plenty of real issues, they also frequently report many false positive findings, especially if you use images and background graphics inserted via CSS.
The ultimate test, of course, is using assistive technology, such as NVDA (external link) for Windows, or VoiceOver (external link) for macOS. Linux also has its own tool, called Orca (external link).
To check the accessibility of PDF documents, you can use either the paid version of Adobe Acrobat Pro (external link), or the free PDF Accessibility Checker PAC 2026 (external link) (Windows only).
