Hey there @Nick,
I took a look and it seems like the only way to fix this would be to increase the width of the various tab panes. I would recommend contacting the folks at Avada to see if they can help do that. It will likely require custom CSS, unfortunately. 🙁
Adding this to the bottom of your theme’s style.css file might help, for example:
.tab-pane.fade.active.in {
width: 100% !important;
}
That might not be perfect, though, so for refinement to get things looking just right, reach out to the Avada folks. If you’re happy to tinker with CSS on your own, definitely check out a [free!] tool like Firebug if you use FireFox, or the Developer Tools for either Safari or Chrome. They have “Inspector” tools that let you zoom right over the element whose styles you want to change, like the tab panes in this situation.
Best of luck with your customizing!
George
