Add a hamburger menu that brings up an overlaid /sitemap to the default skin. check-in: 9c887998 user: drh tags: trunk
2018-09-10
23:34
Add the new "script" element to skins, accessible as /script.js. The idea is to put the hamburger menu javascript from the js-hamburger-menu branch in this script element, rather than inlining it in the footer. But I am not certain that is the best way to go so this change is parked on a branch for now. check-in: e5dbc612 user: drh tags: skin-script
