TYPO3 Instance Reaches WCAG 2.1 Standard Through BITV Test

TYPO3 Bootstrap Package (frontend theme) officially accessible

The TYPO3 Project is proud to have reached a milestone in its development: The TYPO3 Bootstrap Package (frontend theme) is officially accessible after being tested by the German certification body BIK. The TYPO3 community, in close cooperation with CPS agency, helped achieve the international standard WCAG 2.1 and EN 301 549.

Berlin/Düsseldorf, Germany – 29 August 2023

Based on the Introduction Package, TYPO3's Bootstrap Package (with its frontend theme) has successfully passed the conformity test for accessibility by the German test center, BIK. The TYPO3 content management system (CMS) has reached a milestone in terms of digital accessibility with the BIK-BITV test results, after working diligently to improve the Bootstrap Package as well the TYPO3 backend. While the implementation of the international requirements of WCAG 2.1 and EN 301 549 is country-specific, in Germany the BITV and WCAG conformity tests are based on a common procedure.

A significant improvement on the accessibility of digital offers

The TYPO3 Bootstrap Package offers a pre-configured frontend theme for TYPO3 based on the Bootstrap CSS Framework. The Bootstrap Package already supported assistive technologies such as screen readers, magnifiers, Braille displays and voice recognition. Now officially certified, the Bootstrap Package serves as a guide for users on how to effectively implement accessibility in their TYPO3 projects. This significantly improves access to digital offerings and makes it easier for people with disabilities to use them.

Alongside usability, responsive design, security, performance and SEO, accessibility is a quality feature that contributes to the sustainability of TYPO3. "True accessibility is dependent on the website content, which has to be made accessible by website editors on a daily basis," says Daniel Fau, CEO of TYPO3 GmbH. "The seal of approval from the testing authority is a tribute to our entire CMS, its ecosystem, and the dedicated service providers and developers who have contributed to this success. Our vision is that websites created with TYPO3 are accessible to all and that an inclusive online world is achieved through accessibility."

Directive (EU) 2019/882 to be transposed into national law as of June 2025

The initial impetus was the research work of a student at the TH Brandenburg. She subjected ten frontend pages of the TYPO3 Introduction Package (a TYPO3 demo version based on the EXT:bootstrap_package, v14) to a BIK-BITV self assessment and identified barriers. The agency CPS – connected to the university through a teaching assignment – then took the initiative to make the entire package accessible. The CPS accessibility team fully tested the TYPO3 Introduction Package for accessibility, listed any existing barriers, and worked through them together with the TYPO3 community during a four-day code sprint in June 2023. At the end of a three-week test, the BIK test center awarded the test seal.

TYPO3 is widely used in Europe, especially in the public sector. Both in the public and commercial sectors, there is an obligation to provide accessible websites. The EU Directive (EU) 2019/882 emphasizes the need to comply with the WCAG 2.1 guidelines by 2025 at the latest to ensure an inclusive online experience. Compliance is not only legally required, but also creates a more accessible online world. Therefore, website operators must conduct regular compliance tests to ensure accessible use.
