15 CSS Properties You Probably Never Use (but perhaps should)

On seomoz, Matthew Inman points to 15 rarely used CSS properties, and why you might want to be aware of if you don't already use them. I have to admit to only using a handful of these, and not with any regularity.

1. clip
2. visibility
3. text-shadow
4. content
5. quotes
6. counter-reset and counter-increment
7. marks
8. page-break-before and page-break-after
9. orphans and widows
10. font-size-adjust
11. font-stretch
12. font-variant
13. caption-side
14. table-layout
15. empty-cells
