XF 1.3 CSS target Android browser

[Case]

I've had a bit of a look and I don't think this is possible without some additional code.

Looking to target people visiting from Android browsers and add some additional css. Is this possible or any suggestions?

Thanks

There are detection addons. Maybe with them you can add Conditional Statements?!
