Hi,

I found a nice solution to get CSS3 only accordions in email's:
http://responsiveemailpatterns.com/patterns/accordions/full-to-accordion.html.

The problem is, that only outlook.com (LOL) is supporting the css3 pseudo class :target https://www.campaignmonitor.com/css/.

This is a big problem for email clients which are supporting @media screen (e.g. Apple Mail 8) but not :target because the accordion content will be closed per default. Is there any way to detect if the email client is supporting the css3 pseudo class :target?

Regards
Philip
