ThemeKit Switch Gallery

The gallery has an auto CSS grid layout using the min-max proerty and the auto-fill keyword so no media queries are required.
The gallery will display images with different aspect ratios in a grid with a lightbox slideshow.
Switch
In default mode the thumbnails are displayed with their original aspect ratio and the captions outside below the image.
Checking the "Regulate Grid" box will arrange the thumbnails into a grid with equal size thumbnails. The rows have a control for adjusting the height. This determines the aspect ratio of the grid.
In the switched position the captions overlay the bottom of the image.
