The body text of IPython for Web Devs is set in Gentium Book Basic, which was designed by Victor Gaultney. The Gentium Book Basic font family is based on the original Gentium design, but with additional weights. The family comes with a complete regular, bold, italic and bold italic set of fonts.
The side chapter text is set in Open Sans, a humanist sans serif typeface which was designed by Steve Matteson. Open Sans was designed with an upright stress, open forms and a neutral, yet friendly appearance. It was optimized for print, web, and mobile interfaces, and has excellent legibility characteristics in its letterforms.
The monospaced font used for code samples is Edlo, which I created by modifying a version of Stephen G. Hartke’s Aurulent Sans, which I thought was beautiful, but hazardous for programming because the similarities between zeroes and ohs and ones and els were too close for comfort.
The book cover was illustrated by lutfihakim394.
The favicon snake graphic was created by Bakunetsu Kaito from the Noun Project.
This book was generated by using mdBook, which is a free, open source command line tool and Rust crate to create books using Markdown (as by the CommonMark specification) files. It’s very similar to Gitbook but written in Rust.
