[oXygen-user] CSS validation warnings

[Frank Dissinger]

Hi Kris and Radu,


I refer to (2): Opening "custom.css" in oXygen.

/Also make sure you prefix the pseudo class value also in the 
oxy_action. /--> How do I do this?

Negative values do have an effect in oXygen's Author mode and they are 
essential for me. Hm...???

I'll investigate to see if "margin-inline-start" is really required or 
can be replaced. I saw that it is used in one of oXygen's CSS files and 
wanted to reverse a formatting effect produced with this style.

Do I use an oXygen framework for my custom.css? Probably... How can I 
verify this?


Regards,

Frank
