Accessible web content
The Web Content Accessibility Guidelines
The "Web Content Accessibility Guidelines (WCAG)" are international guidelines developed by the World Wide Web Consortium (W3C) to ensure that digital content is accessible to everyone, including people with disabilities or limitations.
WCAG principles
The WCAG guidelines are based on four fundamental principles, aimed at creating an inclusive web for all users:
Perceivability
Content must be perceivable by all users, such as through alternative text for images or subtitles for videos. Additionally, clear contrasts and flexible text sizes are essential to ensure readability.
Operability
All website functions must be usable with different input methods, such as keyboard navigation. This includes making interactive elements, like forms or buttons, easily accessible and intuitive to use.
Understandability
Content should be clear and simple to understand, both linguistically and structurally. This includes providing simple navigation, clear error messages, and avoiding complex technical terms.
Robustness
Web content should be compatible with different devices and technologies, including screen readers and future developments. A clean code structure and the use of standardized HTML and WAI-ARIA attributes help achieve optimal compatibility.

Checklist of key aspects
The WCAG guidelines provide comprehensive guidance for creating more inclusive digital content. Our checklist includes central points that can serve as a first step towards improving accessibility:
WCAG versions and conformance levels
The current version, WCAG 2.2, was published on October 5, 2023. As with previous versions, version 2.2 is backward compatible with 2.1 and 2.0. Meeting the requirements for 2.2 also fulfills the criteria for earlier versions. The guidelines are divided into three conformance levels:
Level A
Basic accessibility or minimal requirements are met. Essential content or functions can be accessed and operated by users with visual or hearing impairments.
Level AA
Increased accessibility and the standard for legal requirements in many countries (such as Austria) have been achieved. This level includes measures such as color contrast, alternative input methods, and clear structure.
Level AAA
The highest level of accessibility with strict requirements is optional but recommended for particularly inclusive websites. This includes videos with sign language and extremely simple language.

What is an Accessibility Statement?
An Accessibility Statement is a document that certifies the accessibility of websites and apps for people with disabilities.

How can I check if my website meets the Web Content Accessibility Guidelines?
To check if your website meets the Web Content Accessibility Guidelines, you can use various tools and methods, such as using accessibility tools such as WAVE or WebAIM.
What are the consequences if my website does not meet the Web Content Accessibility Guidelines?
If your website does not meet the Web Content Accessibility Guidelines, it can lead to a range of consequences, such as a poor user experience for people with disabilities, reduced visibility in search engines, a negative impact on your company's image, and even legal consequences. It is, therefore, important that you create a WCAG homepage to avoid these consequences.
