Two wagon wheels rotate continuously on a blank page, each built from a circular black border and six spoke lines radiating from its center. The left and right wheels spin independently in opposite positions on the screen, using CSS `@keyframes` animation with an infinite linear spin of 360 degrees over three seconds. Each wheel’s spokes are styled divs positioned with `transform: rotate()` increments of sixty degrees, leveraging the `nth-of-type` selector to arrange them. The example relies solely on HTML and CSS, with no JavaScript or external libraries.
