I am HTML/CSS/jQuery coder. And I need to develop the website, which will be "zoomed-out" or "fitted" to 320x480 (frequently used resolution) Android mobile device screen. Or even this solutions should check my screen resolution and connect the right CSS for that. Somewhere I met that there is android.js file, which connects to HTML and recognizes if the website was open on PC or on android device. But I am not sure at all. I didn't do anything for mobiles before.
Found this article: http://blog.mgpwr.co.uk/2010/09/make-your-website-iphone-compatible/ Don't think it's a right solution to use PHP for that. Better would be HTML or JS.
