How to have the Latest Post thumbnail images have rounded corners

Hi,

Thanks for contacting us here about this extension.

How can I make the thumbnails for the latest posts to have slightly curved corners/border?

We do not have that option. However, you can adjust by going to Advanced tab > Custom CSS, and put this code:

.wplp_widget_762 span.img_cropper 

{

border-radius: 20px;

}

"762" is the block ID.

Hope it helps!
Cheers,
