See all 404Where to use it
News sites, weather apps and local media can turn their error page into a television weather map. Beige coastlines sit on a teal sea, dashed isobars circle a spinning storm symbol labeled 404 hPa, a sun turns slowly, a cloud drifts and the temperatures only read dashes.
Along the bottom, a warning ticker scrolls the chance of finding this page, which is zero. Everything is inline SVG and CSS keyframes, and reduced motion freezes the map. Adjust the orange accent of the warning label and point the button home.
