This section of the developer’s manual discusses aspects of usability and accessibility as it pertains to Joomla!

Our brief definition of Accessibility and Usability:

Accessibility:

Determines if the site and its content can be accessed by people with various disabilities.

Usability:

A measure of how easy it is to use a particular website, whether or not a user has a disability.

We will also discuss other web standards and best practices.

In other words:

• Accessibility is focused on the access needs of people with disabilities.
• Usability is focused on everyone's access needs.

By focusing on both accessibility and usability, we are aiming to make sites that everyone can access, including those using older/different technologies (hardware, software, connections), or other "specific" needs.

We accomplish both by using standards such as (x)html, css, wcag/508, and following best practices.

In theory, an accessible site is a usable site, but that is not always the case. This is why it is important to consider both accessibility & usability.
