Responsive Design
Plain-language definitionAn approach where layout and interaction adapt to available space, device capability, and input method. It is more than shrinking a desktop page.
Why it matters
Use the term to make a better decision.
In practice, responsive design matters when a team needs to connect a technical or creative choice to a visible change in clarity, performance, discovery, or conversion. The useful question is not whether the term sounds sophisticated. It is what decision it helps the team make.
