News applications editor Scott Klein
has written a "ProPublica News Apps Style Guide
" that codifies "the typographic and technical best practices" its developers follow.
Much like the AP Stylebook, the News Apps Style Guide helps journalists resolve uncertainty and avoid common mistakes by providing guidance on the most important or often misunderstood points.
Also like the AP Stylebook, the News Apps Style Guide contains an alphabetical list of subjects -- from Accuracy to Updates (no "z-" words yet) -- with a brief discussion and guidance for each.
should your news app be sure to work in? "The current and prior major release of Chrome, Firefox, Internet Explorer and Safari on a rolling basis" as well as "the built-in browsers in the latest revision of the iOS and Android [SDK]," and "if earlier releases represent more than 2.5% of our audience, continue to support them."
