/*
 * Styles of z1Dialog (dialog.js). Markup dialogs use the same structure as the generated ones:
 *
 * <dialog class="z1-dialog [z1-dialog-sm|z1-dialog-lg]">
 *     <header class="z1-dialog-header">
 *         <h2 class="z1-dialog-title">…</h2>
 *         <button type="button" class="z1-dialog-close" data-z1-dialog-close aria-label="Close"></button>
 *     </header>
 *     <div class="z1-dialog-body">…</div>
 *     <footer class="z1-dialog-footer">
 *         <button type="button" class="z1-dialog-button" data-z1-dialog-close="cancel">Cancel</button>
 *         <button type="button" class="z1-dialog-button z1-dialog-button-primary" data-z1-dialog-close="ok">OK</button>
 *     </footer>
 * </dialog>
 *
 * The look can be adapted through the custom properties below, e.g. in a `:root` or `.z1-dialog` rule. A title
 * icon needs room next to the title, e.g.:
 *
 * .z1-dialog {
 *     --z1-dialog-title-icon: url('/img/favicon.ico');
 *     --z1-dialog-title-icon-space: 25px;
 * }
 *
 * A relative url() in a custom property is resolved relative to this file, not to the stylesheet setting the
 * property, so use absolute URLs there.
 *
 * `z1-dialog-button` also styles links, e.g. download links in the footer.
 *
 * While a modal dialog is open, the page behind it doesn't scroll: its scrollbar is hidden, and z1Dialog.open()
 * keeps the scrollbar's width as padding of the root element, so that the page doesn't shift sideways.
