When looking at the full bibliographic display of a record in the opac on a mobile device, the display is confusing to patrons as the information is not presented in a table as it is when viewing on a laptop or PC browser screen. All table headings are missing - Home library, Current location, Status, Barcode etc. It looks like the Bootstrap framework drops the table headings when displaying the information on a tablet or mobile phone device. This can cause confusion for the patrons especially if the home and current libraries are different. The libraries are just listed one underneath the other which can also cause confusion as patrons may think that there are 2 copies rather than it just being the holdings statement for one copy.
This is still valid on master, and causes a lot of confusion with library patrons.
I just tested and in 22.11 it looks really strange. The table headings are not removed, but all overlap and the text in the cells moves to read from top to bottom... The display is unusable like this as you can't read the headers nor the content. It's much better in master - not sure what the difference is?
I think this has been fixed by the addition of the DataTable responsive plugin.
