What is responsive design?
One website that reshapes itself to fit any screen (phone, tablet or desktop) instead of separate sites for each.
Responsive design is the practice of building a single website that adapts its layout to whatever screen it’s viewed on (a phone held in one hand, a tablet, a wide desktop monitor) so it always looks intentional and stays easy to use.
Why it’s non-negotiable
More than half of web traffic is on mobile, and Google ranks the mobile version of your site first. A site that only works on desktop is, for most visitors, a site that doesn’t work.
How it works
Rather than fixed pixel widths, responsive layouts use flexible grids, scalable images and breakpoints: points where the design rearranges itself, so columns stack, navigation collapses and type resizes. The content stays the same; the composition adapts.
Good responsive design isn’t just shrinking
It’s deciding what matters most on a small screen and making sure that comes first. The phone experience often is the main experience, so it deserves to be designed deliberately, not squeezed down as an afterthought. It goes hand in hand with accessibility and page speed.
