How does an accessible website work? Explanation without jargon
What actually happens technically when an accessible website runs in your business — explained for decision-makers, not developers. Including the points where people are still needed.
Accessible website works like this at its core: A request comes in, is checked against stored content and rules, and is either answered directly or handed over to a person with full context. The real work isn't in the technology, but in defining exactly where that boundary lies.
01 — How it works
How an accessible website works technically
A site compliant with WCAG 2.1 AA with documented test results and fixed issues.
From the outside, here's what happens: A request comes in — through the website, phone, a form, or an existing system. It's captured, checked against the stored rules and content, and either answered directly or handed over to a person with full context. The critical part isn't the technology, but defining where that boundary lies.
Since the accessibility law, accessibility is no longer optional for many online services. Most sites already fail at keyboard navigation. This exact point determines how the system is configured — not a generic product promise.
02 — Components
What the system consists of
- Testing against WCAG 2.1 Level AA, automated and manual
- Keyboard operability throughout the entire flow, including forms
- Contrast, font sizes, and focus indication
- Meaningful alt text and correct heading structure
- Forms with labels and clear error messages
- Audit report and accessibility statement as documentation
03 — Process
The steps in detail
Audit
Automated testing finds about a third of the issues. The rest requires manual testing — keyboard, screen reader, magnification.
Prioritize
What blocks use, what is a cosmetic flaw. That's the order in which issues are fixed.
Fix
Implementation, mostly in design and markup, less often in functionality.
Document
Re-audit, report, and accessibility statement for the website.
04 — Questions
Frequently asked questions
What happens in case of violations?
The Sozialministeriumservice is responsible. Administrative penalties of up to 80,000 euros are provided for. In the initial phase, the focus was mainly on advice rather than penalties, but that's no guarantee for the future — proceedings are already underway.
Is an accessibility overlay sufficient?
No. These overlays do not fix the underlying problems and are largely rejected by disability advocacy groups. They can even create additional barriers. Accessibility is created in the markup, not in a layer on top.
What is the most common error?
Forms without linked labels and controls that cannot be reached with the keyboard. Both go unnoticed by anyone working with a mouse — and make the site unusable for others.
Does this also apply to PDF documents on the website?
Yes, if they contain essential information — such as price lists or downloadable forms. PDFs must also be structured with alternative texts.
How much work is involved for an existing site?
It varies widely. A well-built site often only needs contrast corrections, alternative texts, and focus indicators. A site with custom-built controls without keyboard support can be more work than building from scratch.
Can we implement this step by step?
Yes, by priority: first the defects that completely block usage, then those that make it difficult. This can be spread across several stages without taking the site offline in the meantime.
How long does a complete audit take?
For a medium-sized website, one to two weeks, depending on the number of different page types and interactive elements such as forms or filters.
05 — Decision
How to move forward
The most affordable next step is a conversation, not a quote. Twenty minutes is usually enough to clarify whether a project makes sense, what scope it involves, and whether we're the right fit.
If we're not, we'll say so. An honest no costs less than a project you abandon after three months — for both sides.
