<!--
  In the table below, if you make all 3 CSS rules the same pixel height, then the vertical spacing 
  will be consistent across all browsers, including MS Outlook 2007+ rendering engine:
        <td> height: 16px
          font-size: 16px
        line-height: 16px
  
  These conditions must be true:
    1. "mso-line-height: exactly" is set
    2. you have a non-breaking space (or Unicode '&#xA0') in the <td> tag
    3. you put your CSS rules in the <td> tag

  Basically, this workaround table is to avoid the undesirable behavior of Outlook collapsing white space
  around some types of block-level elements, including <img>, <p>, and <div> tags.
