Edit: Since none of the major engines actually implement strict mode, I'll rephrase slightly: Is strict mode intended, amongst its other goals, to allow browsers to introduce additional optimisations or other performance enhancements?

• Responsive width for iPhone

  - by Alex Marchant

  This is my first time building a responsive site, and as I tailor the CSS for the iPhone I'm running into a problem. The styles all apply correctly, the text changes size and the wrapper changes widths. The problem is the iPhone browser still opens up at a huge width, see the screenshot: I'm using @media all and (max-device-width: 480px) {} to set the specific iPhone css. body {width:;} doesn't work. Thanks for the help :)
