This is a nice little SVG and HTML animation for a toggle switch, it has a day and night mode. During the day the background of the toggle has clouds moving right to left and a starry night sky as the switch and on click, the starry night expands and switches over to the other side swapping the toggle and background animation. Works well for weather sites with checkboxes.
