The author's web site (http://rigoneri.com/) is cited as an example "Syte", but when I view that page on my iPad the right-hand side of the page is chopped off. Doesn't seem to be all that responsive (despite the author's claims).
It's at specific widths. I've seen other responsive sites behave like this and I presume it's just something with the media queries in the style sheet. If you continue to narrow your browser you'll see that it does respond correctly.
I dont think so. Im using hackernews app on iOS,which displays your page truncated and unusable. Responsive means all widths are possible, not just some of the more common ones.
Related, on http://rigoneri.github.com/syte/, down the page where it talks it about Responsive, it shows two images side-by-side.
One is clearly an example of responsive on a phone or tablet, but the other appears to be an example of broken responsive where the content got truncated as the OP of this thread mentions?
I don't know what this fix included but I can't see part of the text in my browser (about 1100 width). There should probably be some margin on the right side as well so text doesn't touch the border (or overflow).
