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 Vertical Tabs:
On larger screens, tabs display vertically to the left 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 recommends using vertical tabs when many tabs are required to organize information on a single page.
