Unless someone has a better idea, I will be using the CSSGrid with the flex properties, etc. It will have a header, footer, navigation indicator, and data presentation areas.
During the presentation of a question, the user may press a button for more information, or to get an extended list of answers, etc. that would be displayed over the presentation of the original question.
Cards, modals, toasts, jumbotron - all seem to allow data to be displayed and even entered. Which are best for what purposes?
