/*
 * The toggle is triggered on touch devices by two methods:
 * 1. Using `:focus` and tabindex
 * 2. Using `:hover` and a `touchstart` event listener registered on the document
 *    (Doesn't work on Surface touch devices)
 *
 * Note: Transitions don't work with `uk-postion-center-*` classes because they also use `transform`,
 *       therefore it's recommended to use an extra `div` for the transition.
