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:
ʇxǝʇ uʍop ǝpısdn ǝʇıɹʍ
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 :)
