title: Can the content of a CSS Pseudo element made visible to copy/paste?
body: <p>I'm accessing a page with stylesheet containing an entry like this:</p>
  <pre class="lang-css prettyprint-override"><code>.label::after {
    content: ':';
  }
  </code></pre>
  <p>As expected, elements styled with class 'label' appear in the browser with a colon following them.  However, when I use the mouse to select a region containing this, the colon is not highlighted with the rest of the text.  More importantly, the colon is not copied to the clipboard.</p>
  <p>Is there any way to use CSS for a browser to include the colon character when copying to the clipboard?</p>
