Upside down text with CSS

Previously I’ve talked about reversing text with CSS by simply setting a few CSS attributes. Today we will try another trick: turning text upside down.

It’s actually possible using a simple CSS property and works cross-browser today. The property to use it “text-gravity” with a value of “inverse”.

<span style="text-gravity: inverse">
write upside down text
</span>

… and this is the result:

?x?? u?op ?p?sdn ?????

I’m really surprised to learn that so few people know about this property, and I recommend you to continue reading the W3C specification of text-gravity.

Update: Sorry, I lied :) The above is done with a UTF-8 character generator (see the link the the “specification” above). Amazingly, you can find that most characters have their upside down equivalent somewhere else in the huge Unicode alphabet. Neat trick :)
