Thanks for such a swift reply. I feared this might involve CSS about which I know very little – is there anything that will help me understand what it means to “override these with CSS classes”?
Is that on WP (where https://en.support.wordpress.com/custom-design/editing-css/ may help me I guess) or given you say it is based on the style guidelines on Zotero is it something I need to change there (is https://www.zotero.org/support/dev/citation_styles/style_editing_step-by-step what I need to get into?).
Will look into making notes public and see if that helps with the other problem.
Really grateful for your advice and the plugin. Thanks.
