Css code for rounded corners featured images blog items

Site URL: https://crow-manatee-3gjr.squarespace.com

I'm working on a new website. All the images in the new website have rounded corners but it's not possible within Squarespace for the featured images. Can anybody help me with coding these corners? It's for the featured images on the blog items / pages.

If you switch to using summary blocks as your front facing blog page, then you have a lot of control over the items in the block. Here is some code I use to change the block items to just about any shape by adjusting the border radius along  with a box shadow:

.sqs-block-summary-v2 .summary-item {
  background-color: #ffffff;
  border-radius: 15px 70px 15px 70px;
  -webkit-box-shadow: 0px 0px 15px rgba(100, 100, 100, 100.1) !important;
  -moz-box-shadow: 0px 0px 15px rgba(100, 100, 100, 100.1) !important;
  box-shadow: 6px 5px 15px rgba(100, 100, 100, 100.1) !important;
}

Try this in the Custom CSS, you'll have to adjust the pixel radius to suit your design:

.sqs-block-summary-v2 .summary-thumbnail {
  border-radius:20px;
}

 

Thanks a million!!! This works for me!
