How can I draw vertical text with CSS cross-browser?

Updated this answer with recent information (from CSS Tricks). Kudos to Matt and Douglas for pointing out the filter implementation.

.rotate {
  -webkit-transform: rotate(-90deg);
  -moz-transform: rotate(-90deg);
  -ms-transform: rotate(-90deg);
  -o-transform: rotate(-90deg);
  transform: rotate(-90deg);

  /* also accepts left, right, top, bottom coordinates; not required, but a good idea for styling */
  -webkit-transform-origin: 50% 50%;
  -moz-transform-origin: 50% 50%;
  -ms-transform-origin: 50% 50%;
  -o-transform-origin: 50% 50%;
  transform-origin: 50% 50%;

  /* Should be unset in IE9+ I think. */
  filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=3);
}

Old answer:

For FF 3.5 or Safari/Webkit 3.1, check out: -moz-transform (and -webkit-transform). IE has a Matrix filter(v5.5+), but I'm not certain how to use it. Opera has no transformation capabilities yet.

.rot-neg-90 {
  /* rotate -90 deg, not sure if a negative number is supported so I used 270 */
  -moz-transform: rotate(270deg);
  -moz-transform-origin: 50% 50%;
  -webkit-transform: rotate(270deg);
  -webkit-transform-origin: 50% 50%;
  /* IE support too convoluted for the time I've got on my hands... */
}

I am using the following code to write vertical text in a page. Firefox 3.5+, webkit, opera 10.5+ and IE

.rot-neg-90 {
    -moz-transform:rotate(-270deg); 
    -moz-transform-origin: bottom left;
    -webkit-transform: rotate(-270deg);
    -webkit-transform-origin: bottom left;
    -o-transform: rotate(-270deg);
    -o-transform-origin:  bottom left;
    filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=1);
}

My solution that would work on Chrome, Firefox, IE9, IE10 (Change the degrees as per your requirement):

.rotate-text {
  -webkit-transform: rotate(270deg);
  -moz-transform: rotate(270deg);
  -ms-transform: rotate(270deg);
  -o-transform: rotate(270deg);
  transform: rotate(270deg);
  filter: none; /*Mandatory for IE9 to show the vertical text correctly*/      
}

If CSS writing-mode: sideways-lr is what you prefer, and you happen to run into chromium/chrome based browser. You may try

{
  writing-mode: vertical-rl; 
  transform: rotate(180deg);
}

so all modern browsers support it now.
