title: Select whole text with one click
body: <p>I have a shareable link in my app and I would like to make it selectable in one click for the users to copy it.</p>
  
  <p>How can I achieve that in a browser-native manner?<br>
  (I'm not interested in a javascript solution at this stage)</p>
  
  <p>Is there an HTML5 attribute I can use?<br>
  Is there a CSS thing I can use?</p>
