title: Tapping links in iOS Safari shows a thick white border around element - how to get rid of it?
body: <p><em><strong>Problem</strong></em></p>
  <p>On my site I see this super strange behaviour on any kind of linked elements (text, images, svg elements, table cells): when long tapping them in Safari on iOS, a thick white border appears before showing the link preview.</p>

  <p><em><strong>What I have tried so far</strong></em></p>
  <p>As it's only showing on iOS, I am a bit limited with debugging it, unfortunately.</p>
  <p>I have tried to fix it using the following most recommended solutions with link tap in iOS Safari, but neither of them does solve the issue:</p>
  <pre class="lang-css prettyprint-override"><code>html {
      -webkit-tap-highlight-color: transparent;
  }
  a, a:visited, a img {
      -webkit-background-clip: content-box;
  }
  input, textarea, button, select, label, a {
    -webkit-tap-highlight-color: rgba(0,0,0,0);
    -webkit-tap-highlight-color: transparent;
  }
  </code></pre>
  <br>
  <p><em><strong>Solution ideas?</strong></em></p>
  <p><strong>Does anybody know, or has an idea, how I can get rid of this border</strong> - or at least also make it appear &quot;transparent&quot;?</p>
  <p>Much appreciated!</p>
