The Magic of Native popover

Have you ever wished for a native way to create modals, popovers, tooltips, dropdowns on in general overlaying stuff without relying on JavaScript? The HTML Popover API is here to change the game, giving us an elegant, accessible, and declarative solution!

Introduction

The popover attribute in HTML introduces a built-in solution for pop-ups, eliminating the need for extra JavaScript. Unlike traditional overlaying elements that require event listeners, popover integrates seamlessly with CSS and offers automatic dismissal behavior, making it both accessible and lightweight.

?? Theory: How popover Works

1. Declarative & Simple
2. Automatic Dismissal
3. Flexible Styling with CSS
