Design/Archive/Wikimedia User Interface/Use cases/Font family stack

There are two main font family CSS stacks in Wikimedia products, a serif one and a sans-serif one.

This article focusses on the history and current stacks in use (as there are slight alternations here and there):

Serif font family – logo, first and second order heading
In base.css we've come to
 * "Linux Libertine", Georgia, Times, serif Origin: base.css, Minerva, Blueprint
 * 'Linux Libertine', 'Hoefler Text', Georgia, 'Times New Roman', Times, serif Origin: Wikimedia Portal, 'Hoefler Text' was used for old logo before 2010, originally invented 2005

Sans-serif font family – sub-headings h3–h6, running text
In base.css we're currently going with
 * "Helvetica Neue", Helvetica, "Nimbus Sans L", Arial, "Liberation Sans", sans-serif Origin: base.css, Minerva
 * sans-serif Origin: Vector variable.css  Reason: https://phabricator.wikimedia.org/rMWdc64e337a308cdbf50037835d8e456ff30b3b8d5
 * "Helvetica Neue", Helvetica, Arial, sans-serif Origin: Blueprint, should have been same as Vector?!

Bugs (historical)

 * `sans-serif` in Vector due to issues with "Liberation Sans" on Windows in 2014-07 before it was
 * Arimo, "Liberation Sans", "Helvetica Neue", Helvetica, Arial, sans-serif but people also raised concerns against "Helvetica Neue", Helvetica, Arial, sans-serif. https://phabricator.wikimedia.org/T65512 (Note to myself, wondering about the stack featuring "Liberation Sans"/"Helvetica Neue" first versus behind Arial) VEckl (WMF) (talk) 23:51, 4 April 2016 (UTC)
