Our community partner would like to move the name of each story’s author to the bottom of the story instead of the top (they have good reasons). It doesn’t seem you can move that element in any of the standard theme settings. I’m guessing this would be a CSS modification?
You would need to manually edit code in the PHP files to relocate the bylines.
If you simply want to hide them, you could use CSS.
The following should hide them from every page where they appear (item page, search, browse, homepage, etc.):
.byline{display: none !important;}
To only hide on the item page, use:
#items.show .byline{display: none !important;}
PS: this applies to the Curatescape Echo theme specifically
