Html – How to disable viewport zooming on Mobile Safari

htmliosmobile-safariviewportzooming

I've tried all three of these to no avail:

<meta name=”viewport” content=”width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;” />

<meta name=”viewport” content=”width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=false;” />

<meta name=”viewport” content=”width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=no;” />

each are different values I found recommended by google searching or SO searching, but none of the 'user-scalable=X' values seem to be working

I also tried comma delimiting the values instead of semicolon, no luck. Then I tried ONLY having the user-scalable value present, still no luck.


UPDATE

Got this from Apple's site and it works:

<meta name="viewport" content="width=device-width, user-scalable=no" />

it turns out that the problem was the non-standard quotes because I had copied the meta tag from a website that was using them, whoops

Best Solution

Your code is displaying attribute double quotes as fancy double quotes. If the fancy quotes are present in your actual source code I would guess that is the problem.

This works for me on Mobile Safari in iOS 4.2.

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
