Thanks. I tried a lot of combinations including your suggestion, which is actually in the current version online.
Somehow the <meta> line doesn't do anything for my site. I use it right here:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="viewport" content="width=device-width; minimum-scale=1.0; maximum-scale=1.0" />
Any idea why?
