/* This is pretty advanced CSS and is intended to be ready-to-use. Just
 * set an input of type checkbox to class 'toggle-switch' to make the
 * control look like a switch instead of a checkbox.
 * Example:
 *     <input type='checkbox' name='cb1' class='toggle-switch'/><label for='cb1'>Lights</label>
 *
 * Adapted from: https://codeconvey.com/convert-checkbox-to-toggle-button-css/
 * with important adjustments to make it senstive to the local font size.
 * and the addition of comments.
