Graphic design

The graphic charter was defined and created with accessibility in mind. Contrast and color superimpositions have been designed to ensure that the visually impaired have no reading difficulties.


The editorial content of the site has been designed to allow everyone to understand its contents, using language that is as simple as possible given the technical nature of some pages.

Multimedia and video

This site provides a textual alternative to non-textual elements. When your mouse hovers over a visual, text describes the content of that element. The same information is available to voice synthesizers. We use little or no JavaScript code, and when it is used, we offer an alternative.

Les vidéos disposent de sous-titres et d’une audio-description optionnels, ainsi que d’une transcription textuelle.
