Digital training courses using the Multi-support or multi-device option are, as their name suggests, courses that can be adapted to any type of support. In other words, they can be adapted to different screen sizes, whether the screen is small, medium or large. Whether the learner uses a computer, a smartphone or a tablet, he or she will therefore always be entitled to a display that is adjusted and comfortable to look at. The technique used to adapt digital training to different media is called “responsive”. It is linked directly to the programmed code. The developers then take care of this adaptation.
