A meta tag might fit this page into tablets and smartphones
The issue is this. This is a small site, it would not make sense to make a version for smarthphone. So a meta tag might help the page to be rendered correctly on those devices ...
The meta tag is this one: <meta name="viewport" content="width=device-width"> It should make the page fit on any device on theory. We already tested it here and there and the page does not renders properly at once but with a single quick resize with the fingers it fits right there on the phone screen. WE have to look the page to be rendered correctly at once but still it is an improvement. Another thing for this site not to go with a smarthphone version is that the page itself is not big. And the phones are getting bigger. Whatever now it is a bit better than before fitting into those devices screens!
