html5 - meta name="viewport" doesn't work as expected -

Let me write that meta tag in my website www.ssd-vergleichen.de

  is ; Meta name = "viewport" content = "width = device-width; initial-scale = 1.0;" />   
 To prevent the device from initial zooming to the website. When the website is viewed on my Chrome mobile browser on Samsung Galaxy S2, the website has zoomed in about 400%. what did I do wrong?  
 Edit:  
  & lt; Meta name = "viewport" content = "width = device-width, initial-level = 1.0" />   
 It works in Android's standard webbrowser, but still not in Chrome. I wonder if it works in iOS?  
 Editing 2: No, it does not work even with iOS  
    
 
 
 Have you tried  
  & lt; Meta name = "viewport" width = "device-width" & gt;   
 As I understand  width = "device-width" , the width of the layout binds to the width of the device, surely  intermittent-scale = 1  setting is asking the browser to zoom in to 100% (not scale)?  
  Update   
  & lt; Meta name = "viewport" content = "width = device-width, initial-scale = 1;" />
