About varnish
The Carpentries' lesson skin, rebuilt on Bootstrap 5 with dark mode and a wider reach.
varnish supplies the HTML and CSS styling for Carpentries lessons. The defining release in this window is 1.0.3, which moved the theme to Bootstrap 5.3.2, implemented dark mode, made analytics configurable and taught the all-in-one search to distinguish learner from instructor views. Since then the work has been consolidation: dark-mode bugs, Sass variables for fonts, per-carpentry favicons, and fonts that render Ukrainian lessons.
