HTML Dialog Generator
Configure dialog options and copy native HTML dialog element snippets.
Native HTML dialog
The <dialog> element provides built-in focus management and optional modal behavior when opened with
HTMLDialogElement.showModal(). This generator builds accessible markup including an optional
<form method="dialog"> close control.
Scripting
Add buttons in your app that call document.querySelector('#your-id').showModal() and
.close() when finished. Polyfills are rarely needed in modern evergreen browsers. For progress indicators, check out the
HTML Progress Generator, or use the
HTML Text Input Generator for form input fields.
For gauges and measurements, see the HTML Meter Generator.
Frequently Asked Questions
Should I include the open attribute?
Use open for dialogs visible on page load. For modals opened from JavaScript, omit open and call showModal().
What does method="dialog" do?
Submitting the form closes the dialog and sets the return value from the button value attribute.
Can I style the backdrop?
Yes, with the ::backdrop pseudo-element in your CSS when the dialog is shown as a modal.
