Modifying the Styling of Plans list / Registration page

I am trying to get some better styling of my registration page. Its way to vertical for our needs. I dont want break anything by adjusting default template css but I cannot seem to find another option..any suggestions/feedback would help.

We have the functionality down just trying to make it pretty now (columns across and or tabs) I see there are other templates for CB subs but I am not sure how to apply them/install them. All i see is Default when I got to: CB Paid Subscriptions: General plugin settings>Template tab

Am I looking in the wrong place?
Do I need activate or install? if so how/where?
Can i see previews of bootstrap or rounded in action anywhere?
Any examples of working template styles that look clean (like yours CB looks great )

Your template needs to be install-able. See the rounded template included with the CBSubs package for proper XML setup and packaging. Once your custom template is installed you'll be able to select it from CBSubs backend. If all you want is CSS changes however it's best to make additions to your Joomla template CSS file to restyle it however you want to avoid losing your changes when upgrading CBSubs.
