I love me some padded link targets and today’s provider is a Working Library.
The site is about books and their connections. Each post references one or more books and the referenced books are aggregated in the right-hand sidebar. When you hover over a book title, the crisp tiny type is immediately enveloped in a big cozy hover block.
I particularly like how the hover reinforces the column dimensions. It’s a sudden punch of structure to the otherwise airy layout.
