In the specimen neighbouring letters join into one continuous bar and a word space interrupts it, so each word becomes its own block. The shapes inside the blocks are slab serif letters with flat, unbracketed serifs and smooth curves, and the figures are old-style, rising and dipping like lowercase. The family has 2 styles, Regular 400 and Bold 700, without italics, and is not a variable font. Its 982 glyphs cover Western and Central European Latin. Typotheque designed the typeface in a project led by Mozilla, whose core typeface Zilla Slab is, and the copyright notice names The Mozilla Foundation.
