Customizing Integrated Portal /apis page

[sivaramappali]

Hi,

Greetings!

Can someone help sharing your experience on customizing the /apis page, or if you ended up creating a similar new page and got a control over it?

I am trying to see if /apis page can be customized with any css to render the default API tiles/mat-cards as a list , with each item allowing to expand to show the API Product description.

Tried something like this in the Theme Editor Advanced but not able to succeed!

#apis.main-div {
  display: list-item;
  margin-left: 1.3em;
  list-style-type: circle;   
}

-----------------


#apis.mat-card{
  display: list-item;
}

Thanks,

SivaRam
