title: Outlook VML, emulate CSS repeat/positioning
body: <p>For our email templates we are currently using the code below to enable backgrounds in some Outlook versions, however, I've been trying to wrap my head around VML to see if it's possible to emulate the CSS properties to some extent, but the little information I find on VML seems incomplete or hard to put into context.</p>
  
  <p>In practice, there are basically just two properties that are mainly of interest, horizontally centered, and repeat-x only. I would assume that these are so basic VML should easily support it, but I can't figure it out it seems...</p>
  
  <pre><code>&lt;!--[if gte mso 9]&gt;
  &lt;v:background xmlns:v="urn:schemas-microsoft-com:vml" fill="t"&gt;
  &lt;v:fill type="tile" src="..." color="#000000"/&gt;
  &lt;/v:background&gt;
  &lt;![endif]--&gt;
  </code></pre>
