Inclusion
Joomla translates to All Together, and this feeling of unity is one of our core beliefs. Inclusion is in our heart, and as a community, we do our best to accept and welcome everyone.
Accessibility is a cornerstone of inclusive design, ensuring that products and services are usable by everyone, including those with disabilities. Joomla's philosophy of "All Together" reflects a commitment to this inclusivity, fostering a sense of unity and belonging within the community. By prioritizing accessibility, Joomla not only adheres to ethical design principles but also expands its user base, embracing a diverse spectrum of individuals and their unique needs.
Our mission
Our main goal is to make Joomla (the CMS and the websites of the organisation) compliant with the Web Content Accessibility Guidelines (WCAG) 2.2 standard AA level. Beyond that, we are commited to improve the usability of Joomla following the principles of clarity and simplicity, consistency and feedback.
