The fix for Outlook (New)

Pre-render transformed states as images or use table layout

The engine still flags this in the fix: An image points to an address no inbox can load (rotated-content.png), so Outlook (New) shows a broken image instead.

after
<!-- Pre-render rotated content as an image -->
<img src="rotated-content.png" width="200" height="200"
  alt="Rotated content"
  style="display: block; border: 0;" />
Show the original
before
<div style="transform: rotate(45deg);">
  Rotated content
</div>
