This is an excellent site for two reasons. One, it is a working responsive design and it is grid based. Two, it has great content. A site “about style, taste and good manners.” Plenty here to peruse if you’re into this sort of thing. Me, not too stylish, and I lack the manners to be confused with anyone of class, but admire those that can pull it off. Wish this weren’t in German, but here’s a translation.
Also, be sure to change your browser window’s size and see how the site responds.
