sorry you are right. i only tried resizing my browser and nothing happened.. the resize effect when resizing the text is nice though. Maybe some more constructive remark then: in a case like this I might have used a max-width to prevent horizontal scrolling. But well, that might of course have other drawbacks. The site looks nice, that’s for sure.
yeah, the use of max-width on elastic layouts has definitely been debated before. In this case, I think the designers intended to maintain the grid layout at any text size. It can be argued that it might be better for users who need large text to retain the grid structure and have the users scroll horizontally and vertically as if they are viewing the content through a magnifying glass. With a mouse that enables scroll-click, this is actually rather convenient.
But it’s hard to tell. In the case of this site, I think they made the right choice.
