  The purpose of this demo is to show how a 
  "days remaining" CTA link could be built.

  The countdown is simulated, and sped WAY up
  since the idea here would be that the day notificaion
  would change once every 24 hours.

  Note there may be visual rendering issues with IE11,
  and count down announcements may need further revisions
  with pre-Chromium Edge.
<div class="sr-only" role="status" id="session_countdown"></div>
<a href="#" class="preview-link" aria-label="7 Days left to sign up now">
  <svg aria-hidden="true" focusable="false" viewBox="0 0 100 100" class="preview-link__timer">
    <circle cx="50" cy="50" r="45"/>
    <circle cx="50" cy="50" r="45" id="countdown_segment"/>
    <text x="34" y="-30" fill="#fff" id="countdown_number">7</text>
  <span class="preview-link__small" role="presentation">Days Left to</span>
  <span class="preview-link__cta" role="presentation">Sign Up Now</span>
  when navigating with virual cursor, NVDA would 
  treat each element within the link as a separate
  virtual cursor stop when using up/down arrows.

  Updating the aria-label on the wrapping <a> element
  will ensure that NVDA correctly announces the link
  as a single string / virtual cursor focus stop.
