How to debug HTML/CSS for iPhone/iPad performance?

Tags: html,ios,css

Problem :

I am creating a page that should work fine on both desktop and mobile.

On desktop I can use Chrome Developer Tool or Firebug to debug/adjust every details quite easily. But how do I make it perfect on mobile?

Is there anyway I can turn my Chrome to a iPhone-sized view?


Solution :

Chrome's debug tools let you set the constraints of the page you're viewing.

  • F12 / right-click [Inspect Element]
  • Click the gear icon (bottom right)
  • Check [ ] Enable under Overrides
  • Set your User Agent, Device Metrics, Geolocation and Device Orientation
