CSS Gallery is a demonstration of the full power of CSS. This interactive photo gallery is built entirely from CSS (compiled from LESS code); there is no Javascript anywhere.

You can select a category from the fully-functional hamburger menu to filter the photos; you can switch between list and thumbnail views using the bar on top; you can click a photo to open a lightbox scaled to your browser window; you can even navigate between photos from within the lightbox.

To get started, select an option from the hamburger menu in the upper right corner, or navigate directly to All.
