clone-element

Clone HTML elements with styles.

Installation

npm i -save clone-element

Usage

import { cloneElement } from 'clone-element'

document.body.appendChild(cloneElement(document.querySelector('h1'))

Features and limitations

• ✅ Clone with styles.

  ⭕️ Default style for native inputs may work unexpectedly, as they ususally rely on browsers' private CSS extensions thus computed styles become not useful under certain conditions.

• ✅ Support styles for psuedo elements (listed below).

  • ::after

  • ::before

  • ::first-letter

  • ::first-line

  • ::marker

  • ::placeholder

    ⭕️ Only works for Firefox. Chrome/Safari do not report correct computed style for ::placeholder.

  • ::selection

• ✅ Copy content from an existing <canvas> element.

• ✅ Include fixes for grouped <input type="radio">s.

• ✅ Copy input values to cloned element.

  ⭕️ <input type="file"> is not supported.

• ✅ Try to synchronize state between <video> elements.

  ⭕️ May not work for cross domain videos without crossorigin and CORS settings.

• ✅ Fix “contextual” HTML attributes like lang/dir/disabled.
