title: Standard style to apply to broken links on a webpage
body: <p>I've searched for a <strong>standard way of styling broken links</strong> on a webpage and only found general references to using the HTML DEL tag and striking through the linked text with CSS (like the Broken Link Checker plugin does in WordPress). From a usability perspective, I think the CSS way could be best.</p>
  
  <p>Is there a standard or at least better way I haven't found?</p>
  
  <p>PS: I'm not looking for a way to find and process broken links.</p>
