Steps to add a Tab Set component from the Engage tab to an empty Placeholder on a Flow Page.
Engage components have their own internal responsive behavior when used in Flow pages. Tab Sets, for example, can change from a horizontal tab set to a vertical accordion menu based on breakpoint. This provides a better user experience on a narrower screen such a smartphone held in portrait orientation.
Adding a background image to a Section on a Flow page is a great design idea. But images are often very complex visually and it can be hard to read text over them.
One way to help the text be more readable is to add a background color with a transparency setting to the text. The background helps the text stand out against the image while the transparency means the image can still be seen behind the text, providing an effect of added depth to your page.
