Misuse of semicolons in meta viewport

In adaptivetheme\templates\html.tpl.php on line 8 you have:

<meta name="viewport" content="width=device-width; initial-scale=1.0">

This is a misuse of the semicolon between device-width and scale, and you should instead use a comma. When you use a semicolon here WebKit browsers will throw an error like "Viewport argument value "device-width;initial-scale" for key "width" not recognized. Content ignored."

Instead, use:

<meta name="viewport" content="width=device-width, initial-scale=1.0">

On a related note, it is absolutely acceptable to swap "1.0" for "1" so that the meta tag might read:

<meta name="viewport" content="width=device-width, initial-scale=1">
