New Jekyll Starter Themes (Minimal, V2) For Classic Static Web Sites @ Planet Jekyll
Hello, I’ve put together two new static site (ready-to-fork) starter themes for “classic” web sites (e.g. just some web pages and not a blog with an archive and comments etc). The more “advanced” V2 starter theme includes: 1) Shared (common) template/page building blocks using _includes e.g. head.html, header.html, footer.html etc. 2) CSS preprocessing using Sass/SCSS e.g. _settings.scss with $link-color etc. 3) Nav(igation) menu (auto-)built using a configuration / data block; And more. Cheers.
PS: Looking for more themes? See the Dr. Jekyll’s Themes directory.
