Native Modal Dialog Using the HTML dialog Element (No JS Library)

A fully accessible modal built with the native HTML dialog element - no modal library, no focus-trap plugin needed. showModal() handles focus trapping and the Esc key automatically, and a CSS @starting-style transition adds a smooth fade-and-scale entrance for browsers that support it. Copy the HTML, CSS and JS below and drop it into any project.
