This should be the list you need:

A question about the tags in style.css:<br>
<br>
<i>Tags: one-column, two-columns, three-columns, left-sidebar,
right-sidebar, flexible-width, custom-background, custom-colors,
custom-header, editor-style, featured-images, post-formats,
sticky-post, theme-options, threaded-comments, translation-ready</i><br>
<br>
I can't find where the list of the approved ones are. Can somebody
help?<br>
<br>
Another one: Is there a reason why I can't put others there? For
example, my theme supports smartphones, so I obviously want to put
"smartphones" in there. And others not covered by the approved ones.
(Yes, I once had a link to that list, but my cat ate it.)<br>
