Accessibility

Introduction to accessibility on the Internet

The Accessibility on the internet ensures that people with different disabilities can access and use online content without any problems. This does not only apply to people with disabilities, but also to older people or people with temporary restrictions. Accessibility enables them to use websites and apps without restrictions and to obtain information.

An accessible website takes into account various needs and limitations, such as visual or hearing loss, motor impairments or cognitive difficulties. It offers alternative presentations of content, easy-to-understand language, clearly visible contrasts and clear navigation.

Accessibility on the internet not only improves the user experience for people with disabilities, but also for all other users. Some of the benefits include improved usability, better findability in search engines and greater user potential. By making their online presence accessible, companies offer all users a pleasant and inclusive experience.

Definition of accessibility on the Internet

Accessibility on the Internet refers to the design and development of websites and online content that are designed to be fully usable by people with different physical, sensory or cognitive abilities.

Accessibility means that information, functions and interactions on a website are accessible to all people, regardless of their technical know-how or the devices they use. It is about breaking down barriers and ensuring that all internet users have the same opportunities to access and use information.

The definition of Accessibility includes various aspects that need to be considered to ensure that websites are accessible to all users. These include, for example, the structure and navigation of a website, the use of text alternatives for images and videos, the consideration of color contrasts for people with visual impairments and the avoidance of technologies or functions that may be obstructive for certain user groups.

Why is accessibility on the Internet important?

Accessibility online is of great importance as it ensures that all people, regardless of their abilities or limitations, have equal access to the digital space. It is about creating an inclusive and accessible online environment for all users.

There are several reasons why the Accessibility is important on the Internet:

1. People with disabilities: Accessibility enables people with disabilities to participate fully in the digital world. Be it visual impairments, hearing impairments or motor impairments, an accessible website enables these people to access information, products and services.
2. Older people: With increasing age, the ability to see and hear often decreases. An accessible website enables older people to continue to participate in digital life and benefit from the advantages of the internet.
3. Usability: Compliance with accessibility standards improves the user-friendliness of the website. Clear structures, simple navigation and comprehensible content make it easier for all users to find their way around the website.
4. Legal requirements: In many countries, there are legal requirements regarding the Accessibility of websites. By meeting these requirements, you avoid legal consequences and ensure compliance with legal regulations.
5. Image and reputation: An accessible website shows that you care about the needs of all user groups and are committed to inclusion. This is a positive image and can improve the reputation of the company or brand.

Legal requirements for accessibility on the Internet

The Accessibility on the internet is not only an ethical obligation, but also a legal requirement. There are various European directives and German laws that oblige companies and organizations to make their websites and online offerings accessible.

The German laws on accessibility

In Germany, in addition to the European directives, there are also national laws that regulate the Accessibility on the Internet. The most important law is the Disability Equality Act (BGG), which was passed in 2002. The BGG requires public bodies and companies with more than 20 employees to make their websites accessible.

The BGG specifies which standards and guidelines must be adhered to when designing accessible websites. These include, for example, the guidelines of the World Wide Web Consortium (W3C) and the Web Content Accessibility Guidelines (WCAG) 2.1. Companies and organizations are obliged to regularly check their websites for Accessibility and to make this information publicly available.

Overall, compliance with the legal requirements for Accessibility on the Internet is essential. Companies and organizations that do not make their websites and online offerings accessible not only risk legal consequences, but also deny people with disabilities access to important information and services.

The EU directives on accessibility

The EU has issued a series of directives on Accessibility on the internet to ensure that all people, including people with disabilities, can access websites, apps and digital content. These guidelines also serve to promote digital inclusion and remove barriers.

The most important EU directives on Accessibility include:

• Web Content Accessibility Guidelines (WCAG): These guidelines define the standards for accessible websites and specify which requirements must be met.
• European legal act on the Accessibility of websites and mobile applications: This piece of legislation aims to ensure a consistent level of Accessibility for public bodies in the EU.
• European Directive on accessibility requirements for products and services: This directive aims to ensure that products and services, including digital content, are accessible to people with disabilities.

The EU directives on Accessibility are an important step towards removing digital barriers and giving people with disabilities equal access to digital content and services.

The German laws on accessibility

The German laws on Accessibility ensure that people with disabilities also have unrestricted access to the internet. The aim of these laws is to ensure digital participation for all people and to prevent discrimination in the digital space.

One of the most important laws in Germany is the Disability Equality Act (BGG). It obliges public bodies to make their websites and mobile applications accessible. Private companies are also encouraged to make their digital offerings accessible.

The BGG stipulates that websites and apps, for example:

• Must be operable by keyboard, as not all people can use a mouse (keyboard operability).
• Should have a clear structure so that content can be easily found and understood (structuring).
• need to provide alternatives for media content, as not everyone can see or hear (alternative texts and subtitles).
• Texts should be easy to read so that people with visual impairments can easily understand them (readability).
• Colors and contrasts must be chosen so that they are recognizable for people with visual impairments (color design).

Another relevant law is the IT Accessibility Ordinance (BITV 2.0), which sets out specific requirements for the Accessibility of websites and mobile applications. Among other things, it contains specifications for color contrasts, font sizes and the use of Alternative texten.

Practical examples of accessibility on the Internet

The implementation of accessible websites and apps is an important step towards an inclusive internet landscape. Accessibility enables people with disabilities and restrictions to participate fully in digital life and ensures that they can access information and services without barriers.
