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 Arrow Tabs:
On larger screens, arrow tabs display horizontally across the top of the tab content area.
Shrink the browser size to see how the arrow tabs rearrange to two rows above the tab content area.
Remote Learner recommends using vertical tabs if there are too many tabs for a horizontal display.
