title: Excel VBA to click item in html div class
body: <p>I'm a newbie working in my first web automation with Excel VBA.
  I was able to make progress so far but got stuck with trying to click on what looks like a button on the website. 
  Please let me know if you can help me, I appreciate it. Thank you!
  The particular element is within the a tag in the below html code:</p>
  
  <pre><code>&lt;div class="sh-c-btn-group"&gt;
      &lt;input name="pf.ok" type="hidden" value=""&gt;
      &lt;input name="pf.cancel" type="hidden" value=""&gt;
      &lt;a title="Sign In" class="sh-c-btn sh-c-btn--primary" onclick="postOk();"&gt;Sign In&lt;/a&gt;
  &lt;/div&gt;
  </code></pre>
