Adaptive content

Content that automatically adjusts its presentation, structure, or level of detail based on the needs, preferences, or capabilities of the user or their device. In accessibility, adaptive content goes beyond responsive design (which adjusts layout) to potentially restructure navigation, substitute media formats (e.g., replacing a video with a text description), simplify language for cognitive accessibility, or re-sequence content for different interaction modalities. True content adaptation requires semantic knowledge about what the content means and how its elements relate, not just how they are visually arranged.
