Scaling a website to 100% of the width / height of the visible area

Question

How to make the content of a web page fully scaled regardless of the width / height of the visible part of the device?

Answer 1

<meta name="viewport" content="width=device-width,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no" />

also works as a meta tag, if you want users to scale the site, just do not use the Minimumscale, maxscale and user-scalable attributes.

Answer 2

In iphone

webview.scalesPageToFit = YES;

All the best.
