Accessible Moodle (implementation guide)

6.5. Animations

No animated graphics are used.

What is meant by this?

Animated graphics in the form of GIF files should not be used in a Moodle course. Animated graphics or GIFs (Graphics Interchange Format) are file formats for graphics that can play a sequence of images in a loop to create a short animation. The loop function means that GIFs are played repeatedly until the person viewing them closes them or scrolls further. Still images can also be converted to GIF format, but this reduces the quality considerably.

Why is it important?

The use of flickering animations should not be used in the design of accessible digital content. Playing in a loop can be very distracting and annoying. As a rule, animated content does not offer the option of pausing or stopping the animation. This makes it difficult for recipients with concentration difficulties, for example, to grasp the content. In addition, fast movements or flickering effects can trigger seizures in recipients with photosensitivity.

How can I implement/check it?

To explicitly avoid the use of GIFs in your Moodle course, you can manually check the content and ensure that no GIFs are present.
