Typefaces
Headings are set in Source Serif 4 and body text in Public Sans, two open typefaces published under the SIL Open Font License and embedded in the site (no call to a font service).
Icons and logo
The interface icons and the ODERSA logo (an open book with three lines radiating from it) were drawn specifically for the association: they are published under the same license as the rest of the site, except for the logo, which identifies the association (see the License page).
