For most businesses today, more visitors will arrive on a phone than on a desktop computer. A website that was designed for a large screen and merely shrunk down to fit a small one usually shows it — text too small, buttons too close together, images that take too long to load.

Designing mobile-first flips that process around: the small screen comes first, and the layout expands gracefully from there. The result is a site that feels intentional on every device, not just the one it happened to be designed on.
