Does the -o-animation vendor prefix exist?

Question

I'm trying to find out if I need to include the -o-animation vendor prefix in my CSS, but I can't seem to find any resources which indicates it exists, and if it does, what versions of Opera it applies to.

Can anyone offer some suggestions?

Answer 1

According to Opera 12.10 release notes, you didn't need the -o- vendor prefix from that version on. Adding -o- was therefore just needed to support Opera 12.0x versions.

Answer 2

The -o-animation vendor prefix is no longer required for Opera, unless you need to support old Opera v12.** versions.

Instead, use the -webkit-animation vendor prefix to support newer Opera.
