Thanks so much. I have it working now. Need to research setting the color of the buttons to correspond to which is selected/active.
Regarding buttons (rather than tabs), in mobile the buttons stack, so that the content gets pushed down out of view, which works against the purpose of the show-hide. I believe that tabs in mobile become a dropdown – is that right? If so, tabs might be better if there are more than a couple of buttons. Is there a link you have that gives guidance about setting up tabs, or is that difficult, which is why Tova suggested the code for show-hide with buttons?
Thanks again.
