Light and dark

Flip this site's light/dark toggle in the header. The first page follows it, live; the other two are pinned to one scheme each with a ?theme= parameter, and stay put.

Following the site

![Put the PiCAN 2 in its shell](../../3d/pican2/pican2-default.3dstep.html){ type=iframe }

Pinned to light

![Put the PiCAN 2 in its shell, always light](../../3d/pican2/pican2-default.3dstep.html?theme=light){ type=iframe }

Pinned to dark

![Put the PiCAN 2 in its shell, always dark](../../3d/pican2/pican2-default.3dstep.html?theme=dark){ type=iframe }

These use the default theme, which has its own background, so the scheme each one is in is easy to see. The PiCAN 2 example uses a transparent theme instead, and sits on the site's background.

Light and dark mode explains the order in which a page picks its scheme, and how a page on another origin is driven with a message.
