Category pages – featured image grid?

Hi there.

I’m intending to purchase the pro version of your theme as the ‘navigator’ template is pretty much what I’ve built. D’oh!
However, I’m a bit too far down the line with this build to start again.
So, what I wonder is if it’s possible to display any category as a simple grid of featured image thumbnails?

Currently, they display individually, full width, with header, meta , large square image etc.
They also only display 10 or so with pagination at the bottom.

So, is it possible to display all of them in say a grid of four across with no meta or text?
This is how I’d like all categories to look (elementor post grid widget)

and this is how they look by default (my custom css has removed the pagination)
http://wearenoisy-co-uk.stackstaging.com/category/all/

This is the css I started with (not final by any means) but it’s not great (I’m no css expert I’m afraid). I basically just keep trying things until it looks the way I want.
.category-all .entry-header, .category-all .entry-summary,.category-all .entry-meta {
display:none;
}

.category-all .post-image {
float:left;
width:25%;
padding:0;
margin:0;
}
.category-all .post-image img {
padding:0;
margin:0;
}
.category-all #article {
display:inline-block;
}

Or, is it possible to utilize the Elementor post grid widget on each category page, which would be ideal.

Thanks very much in advance for any help you might be able to give.
