        <h2>What?</h2>
        <p>
          This function extends the native JavaScript <code>select()</code> (which <a href="https://developer.mozilla.org/en-US/docs/Web/API/Input.select" target="_blank">only works</a> on <code>input</code> and <code>textarea</code>) so that it can be used to select the content of every DOM element you want. 
        </p>
        <p>
          It's written in Vanilla JavaScript (284 bytes gzipped), so you can use it in combination with or without any library. 
        </p>
        
        <b>Works with</b>
        
        <ul>

          <li>any other browser</li>
