By default, Alma Digital collection thumbnails also display as backgrounds for the collection description at the top of the collection web page. Tulane University Libraries decided on a new approach to thumbnail and background design that takes accessibility and legibility into concern. We’ve also selected a larger image size for collection thumbnails (1980 x 780px) so that images would display clearly at both sizes.
Thumbnail
Background
The layout for collection thumbnails uses a solid color block to occupy the left 60% of the thumbnail. A square collection image occupies the right side. The selected collection image should be a minimum size of 780 x 780px for best results.
The color block addresses accessibility and legibility concerns by providing a clean background for text on both the thumbnail and collection description background. To give each thumbnail a unique identity the color block samples a color directly from the collection image.
When selecting collection images for thumbnails, images with negative space or strong focal points are emphasized.
