HTML Popover API
The Popover API provides a native HTML way to create and manage popover content, such as menus, custom tooltips, and dialog-like interfaces, without requiring complex JavaScript for visibility and positioning.
Getting Started
The Popover API allows developers to create lightweight, context-aware UI elements that can be displayed on demand, such as tooltips, menus, or other overlays.
<button id="infoButton">Info</button>
<div id="popoverContent" hidden>
<p>This is a popover content example.</p>
</div>
The example above shows a button and a hidden popover content. The JavaScript below demonstrates how to use the Popover API to display the popover:
const button = document.getElementById('infoButton');
const popover = document.getElementById('popoverContent');
button.addEventListener('click', () => {
if (popover.hidden) {
popover.hidden = false;
button.setAttribute('popover', 'manual');
} else {
popover.hidden = true;
button.removeAttribute('popover');
}
});
CSS can be used to style the popover for better visual presentation. For example:
#popoverContent {
position: absolute;
background: white;
border: 1px solid #ccc;
padding: 10px;
box-shadow: 0 4px 6px rgba(0, 0, 0, 0.1);
}
By combining HTML, JavaScript, and CSS, developers can create interactive and visually appealing popovers that enhance user experience.
