How can I disable ALL viewport zooming for a webpage accessed via IE11 on WinRT?
I'm working on an application that does it's own drawing on a canvas sized to fit the viewport, and provides it's own zoom functionality internally. Having the browser zoom then makes a mess of the canvas.
I've been going through existing answers, and none of them seem to work for this plaform:
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0"/>
or
<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;">
or
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1" />
or
<meta name="viewport" content="user-scalable=no" />
or
<meta name="viewport" content="width=device-width" />
In the <header> all have no effect.
Additionally, I'd like to block double-tap-zooming, but the various jQuery snippets I've seen don't seem to work here either.
Arrrgh, so as soon as I asked the question, I found a solution:
Adding:
html
{
-ms-content-zooming: none; /* Disables zooming */
touch-action: none; /* Disable any special actions on tap/touch */
}
to the CSS for the application page appears to properly block pinch-zoom in IE, and disable any of the special actions triggered by tapping/double-tapping.
