Modal and Dialog Styling
Style native HTML dialog elements and custom modals with backdrop, positioning, and animations.
Native dialog Element
The HTML <dialog> element provides built-in modal behavior: focus trapping, close on Escape, and showModal() / close() API. Style it with CSS instead of building custom modal scaffolding from scratch.
Styling the Backdrop
The ::backdrop pseudo-element styles the overlay behind an open <dialog>. Apply a semi-transparent background: dialog::backdrop { background: rgba(0,0,0,0.5); backdrop-filter: blur(4px); }. No wrapper div needed.
