Prevent iPhone from zooming form? [duplicate]

Answer 1

Just found a simple fix if you're using Bootstrap:

As mentioned in w3s: You can quickly size labels and form controls within a Horizontal form by adding .form-group-lg to the element.

  

    Large Label
    

      
    
  

See second example on this page: http://www.w3schools.com/bootstrap/bootstrap_forms_sizing.asp

Tested it in Safari and Chrome on an iPhone SE and it works like a charm!
