PopupEnhance
It's a pretty simple JavaScript (TS) library (mostly, for personal use) to enhance a popup to make it movable and resizable.
It's only 34 lines to make it movable: makeMovable ↓ and 38 lines to make it resizable: makeResizable ↓
Also, there is en extra code to store the move / resize state in localStorage (popup-enh-extra.ts).
The required CSS is located here: popup.css.
It's available on npm:
npm i @alttiri/popup-enhanceDemo
https://alttiri.github.io/popup-enhance/ (see: main.ts).
How to use
import {getPopupEnh, makeFocusable} from "@alttiri/popup-enhance";
const {makeMovableEx} = getPopupEnh("fancy-demo-app");
const popupElem = document.querySelector(".popup");
const handleElem = popupElem.querySelector(".popup-header");
const {reset} = makeMovableEx(popupElem, "popup-1", {handle: handleElem});
makeFocusable(popupElem, handleElem);"fancy-demo-app"—localStorage' prefix for keys"popup-1"—localStorage' key
The recommended HTML:
<body>
<div id="app"> ... </div>
<div class="popup-root">
<div class="popup" id="popup-1">
<div class="popup-header">Popup Title</div>
<div class="popup-content"> ... </div>
</div>
<div class="popup" id="popup-2"> ... </div>
</div>
</body>The recommended CSS:
// JS imports:
import "@alttiri/popup-enhance/css/popup.css";
import "@alttiri/popup-enhance/css/popup-content.css";
// Or CSS import:
// @import "@alttiri/popup-enhance/css/popup.css";
// @import "@alttiri/popup-enhance/css/popup-content.css";makeMovable
