This is the impressum page, iFlexbox makes horizontal and vertical alignment painless, through the CSS properties align-content, align-self, and justify-content. Foundation includes a handful of classes for these properties, which work with any flexbox-enabled component.

An element with display: flex is a flex parent, and can horizontally or vertically align its children. All immediate children of the flex parent are flex children. A flex child can vertically align itself.
