/*
 * Sidebar
 *
 * The sidebar is the drawer, the item we are toggling with our handy hamburger
 * button in the corner of the page.
 *
 * This particular sidebar implementation was inspired by Chris Coyier's
 * "Offcanvas Menu with CSS Target" article, and the checkbox variation from the
 * comments by a reader. It modifies both implementations to continue using the
 * checkbox (no change in URL means no polluted browser history), but this uses
 * `position` for the menu to avoid some potential content reflow issues.
