With a handful of custom post types and different page layouts, the Harrowsmith Almanac website was a great website to build. A large focus on their stories was the major goal of the site which required some unique css work to highlight the different categories.
Using classes based on the category of the post the colour of the banner would change. The nth-child pseudo rules also came in handy when changing colours on certain pages with lists of partners and contributors.
Like all of my custom built websites we created a beautiful custom login page for the client as well.
