Get a module to float

If I put two modules in the "info" module position they will be displayed on top of each other. Is there a way to get the modules to float so they will be displayed next to each other instead?

You should add some suffix to modules (same for both modules) and add to override.css file code like this :

.mySuffix {width: 50% !important; float: left}

I tried that now and it doesn´t work so well. Look here:

You have to login to see the other module (Jomsocial mod notification). Login with this standard account:

(Click on "Logga in" in the top right corner".)

Username: test2

Password: aqswdefr

After you login you can see that the Jomsocial notfication module still is below the GK Jomsocial stats module.

When I log in I see only TEST 4 in the same line with GK JS Stats module, this is this place ?
