2. Wrap the Date of Birth into a container element.

<span class="ager">1990-08-06</span>

  years_text: "Years Old",
  output: "%a %Y | %M. %D<sup>%s</sup> %y",
  day_first_suffixes: ["st", "nd", "rd"],
  day_global_suffixes: "th",
  text_months: ["Jan", "Feb", "Mar", "Apr", "May", "jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"],
  output_type: "html" // or text
<!-- Output -->
