Thanks for reaching out.
You can do that with V2 Accordion element, please check this for initial information https://theme.co/apex/forum/t/elements-accordion/24717
Just like other elements, it has its own setting for color, size, margin and padding, and so on.
Other settings are available on that top part, just click items, heading, content, or more. Each section have its own setting for the accordion.
I recommend checking our Knowledge Base here for other features. https://theme.co/apex/forum/t/knowledge-base-overview/287
