The design is based on principles of "flat design", i.e. simplicity, minimalism and a strong focus on typography. Especially the latter is a central point, since this digital edition is about one thing above all: text. Therefore, an Antiqua<hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">(PT Serif</hi>) was chosen as the main typeface, which has a "true" italic cut. It is accompanied by a grotesque <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">(PT Sans</hi>) from the same typeface family, which is mainly used in subnavigations, smaller text and meta information. These <hi xmlns="http://www.tei-c.org/ns/1.0" rendition="#i">classic</hi> typographical conventions, as far as they could be reasonably transferred to the digital medium web, were also taken into account in the further design. For example, a flexible text width oriented to the width of the viewport was dispensed - in favor of a fixed one that corresponds roughly to the typographically recommended line length.
