What is the limitation of PDF Export's CSS rendering capability?

[Samuel Medwedski]

I added a simple water mark CSS style to the pdf export for a section to rotate a text 90°:

.watermark
{
  /* Safari */
  -webkit-transform: rotate(-90deg);
  /* Firefox */
  -moz-transform: rotate(-90deg);
  /* IE */
  -ms-transform: rotate(-90deg);
  /* Opera */
  -o-transform: rotate(-90deg);
  /* Internet Explorer */
  filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=3);
  font-size: 24pt;
  color: #FF0000;
}

to rotate a text I have defined the section's PDF Header.

While I see the text in large 24pt and red color, nothing seems to be able to rotate it.

Is there a known list of limitation of what the pdf exporter engine is capable of?

We need some proper watermarking text (no image) as we are shifting from a word template to confluence generated dumps.

Hi Samual,

the very first question I ever asked in this forum was basically the same: PDF-Export: Which CSS properties do work and which ones not?

The main information is this:

(...) "flying saucer" is what stands behind the export function of confluence and knowing that "flying saucer" uses CSS 2.1 gives a good guideline for which CSS properties will work in confluence and which ones not (...)
