{# /** * @file * Default theme implementation for a page wrapper. * * For consistent wrapping to {{ page }} render in all themes. The * "data-off-canvas-main-canvas" attribute is required by the off-canvas dialog. * This is used by the core/drupal.dialog.off_canvas library to select the * "main canvas" page element as opposed to the "off canvas" which is the dialog * itself. The "main canvas" element must be resized according to the width of * the "off canvas" dialog so that no portion of the "main canvas" is obstructed * by the off-canvas dialog. The off-canvas dialog can vary in width when opened * and can be resized by the user. The "data-off-canvas-main-canvas" attribute * cannot be removed without breaking the off-canvas dialog functionality. * * Available variables: * - children: Contains the child elements of the page. * * @ingroup themeable */ #} {% if children %}
