HI AH,
I updated this custom css to fix the accordion title:
.acm-accordion .card-header a {color: var(--heading-color);}
For the Gallery style, this style is not supported by default in JA Agrivita template so if you want to have it from other template (Uber), you need to copy the same folder of this style in **acm ** folder in Uber template.
and paste into: /templates/ja_agrivita/acm/ folder on your site.
P/s: you may need to customize style / JS so it can match the style of JA Agrivita template
