How do I style the related products section on Squarespace?

Squarespace 7.1 auto-generates a related products section below the main product using the .ProductItem-related class. The heading and grid inside can be restyled independently.

Target .ProductItem-related-header for the section title and the nested .ProductList-grid for the card layout. This lets you create visual separation from the main product content.

.ProductItem-related {
  padding: 60px 0;
  border-top: 1px solid #e0e0e0;
  margin-top: 40px;
}
.ProductItem-related-header {
  font-size: 22px;
  font-weight: 600;
  text-transform: uppercase;
  letter-spacing: 0.1em;
  margin-bottom: 30px;
  text-align: center;
}
