Artist and page list image aspect ratio (CSS)

By default the aspect ratio of images shown on list modules with artists or pages listed will be 4:3.

This can be overridden with some custom CSS added in site settings:

Site Settings > Design > Custom Styles

.module-page-image-box:after {
  padding-bottom: 75%;
}

Use the following percentages for the listed aspect ratios:

1:1	100%
4:3	75%
3:2	66.67%
16:9	56.25%
2:1	50%
