Experiment with the responsive design
Responsive design allows your learning environment to work well on whatever device, computer, tablet, or mobile phone, your learners are using to access the site.
Resize your browser or view on a tablet or mobile device to see the responsiveness with Top Tabs:
On larger screens, tabs display horizontally across the top of the tab content area.
Shrink the browser size to see how the tabs jump to a vertical display above the tab content.
Remote Learner typically recommends using vertical tabs if there are too many tabs for a horizontal display, but because Top Tabs jumps to a vertical display above the tab content, it is a matter of design preference.
