I use to have this website bookmarked and now I can’t think of it for the life of me. I know the website is blue. It’s whole purpose is surrounded around showing different types of styles for elements. For example, if you select “Tables” it will bring up a page with small thumbnail screenshots of different types of styles for tables. Likewise, if you selected “Lists” it would show you different ways to style (un)ordered lists.
It’s basically like a simple inspiration website on how other websites style elements and it’s all done by screenshots of the style and a link to the website.
