WHMCS Integration WCP Welcome line breaks

I'm trying to figure out how to control the look of the WCP_Welcome shortcode/widget. I've got it at the top of my site, but can't get it to run in a single line as it does in another widgetised area on the site.

I'm also having trouble setting the css for colours.

Any help would be appreciated.

Thanks.
