We mainly use the Noto Sans project, a modern font available for every language of the world. When possible (mostly for latin languages), we use Footlight for the headings.
If the language of the web page is not English, the trademark logo should be displayed in English in the page header on all pages. This is because the trademark is registered only in English in most countries and using a translation would weaken the protection offered by the trademark.
It is recommended that the translation of the trademark (and the tagline if required) is displayed in a simple plain font, either as a heading above the introductory paragraph of text, or as part of the introductory paragraph text. See the example for German.
We provide some libraries to easily include the design standards in your websites.
