windowSoftInputMode like web site

I'm building a web site app that will be used from Android devices. At the moment, the browser squashes the page when the soft keyboard appears. I rather want it to scroll the page up.

I've read that the property android:windowSoftInputMode in AndroidManifest.xml can be used for Android apps, but I'm looking for an equivalent for a web site.

============

You can reposition the browser when the user focuses on this input

<input name="whatever" id="id" onfocus="window.location.href='#id'; return true;"/>
