Hide activity tags

[Pietro]

For some of my activities I need to use two activity tags.
When I try to hide them, for those activities I continue to see a "," character even with the tags hidden by modifying the css with "display: none;" statement.
The problem is not present with activities with single activity tag. I think the "," is a separator for the two activities.
Do you think I can hide it by modifying the CSS?

thanks
Pietro

I reply to myself.
I hide span.activitytag by inserting a "display: none;" and now all is ok.
