Question

So I am trying to rotate some text for use on a panel (slider) on a SharePoint web page.

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

not supported by the SPS2010 schema? is there a way to get the same thing with older method?

Answer 1

You could create a custom CSS file and add it as a reference to the master page used to format your site.

Erik Swenson has a good overview of the parts of the CSS structure here:

SharePoint 2010 CSS references in Master Pages

Finally here is a page from Microsoft on how to use the Master Page to customize your site:
