Hi
JA Company and Good both are completely different template that use different layout and override for modules.
In Articles category for JA Good we have many layout. If you want to use them in a another template, it need custom work to move these layout files and re code the style part in PHP, css and js code.
http://prntscr.com/124cf6x
All the override file present in "/html/mod_articles_category/brick.php" in template "ja_good".
And style is in the template.css file /templates/ja_good/css/themes/news/ for different themes.
You can find the JS files in the js folder as there are many layout used that use different style.
Hope it helps.
Regards
