>Is there a way to force a browser to work at 100%.


Saw this on StackOverflow search (specifically mentioned iPhone):

<meta id="viewport" name="viewport" content="initial-scale=1.0; user-scalable=0;
minimum-scale=1.0; maximum-scale=1.0" />

And this (http://www.css3.com/css-zoom/):

div { zoom: 200% }
<div style="zoom: 200%">This is x2 text </div>

Or this blog:
