About Vivliostyle

Who we are

Writing is at the heart of civilization. Every step forward in the history of writing has been a major step forward in the history of mankind. The latest one, hypertext and the web, working on any device, in every language, giving a voice to anyone, is bringing profound changes to society, connecting people like never before.

But along the way, something of value was lost. Due to technological limitations, typography and typesetting on the web today remain behind what was common place in printed media. Not merely decorative, many of these styling techniques had been developed over decades, even centuries, to improve the reading experience.

Vivliostyle —from βιβλίο (“book”, in Greek) and style— is here to address that. We take CSS, one of the cornerstones of the web, responsible for how it looks, and extend it to support this rich typography tradition. So that the web can be as nice to read as the nicest books. So the nicest books can be made with web technologies. So that web and print don't have to stay separate worlds.

Lea Verou

Research Assistant at MIT CSAIL, W3C CSSWG Invited Expert, Author of CSS Secrets (O’Reilly Media), Developer of PrismJS, Dabblet, and -prefix-free

Our name “Vivliostyle” was given by her. First we considered Biblio- or Biblos-, and Lea suggested: since ‘biblio’ and ‘biblos’ both come from Greek, you might also want to consider Vivliostyle, which is on par with how the word is actually pronounced in modern Greek (it’s a widespread mistake that the Greek letter beta (β) is pronounced as b, but it’s actually pronounced as v).
Her book CSS Secrets (O’Reilly Media) was typeset entirely in CSS!
