@maustyle Just freaking LOL at people copy-pasting without thinking, then asking questions without thinking.

I have a project where this came in very handy, thanks. In my project, I needed to set have a fixed viewport width, which wouldn't allow me to use the "initial-scale" and "maximum-scale" parameters in the meta tag. Because the scale was not 100%, the address bar in iOS would only scroll up halfway, due to the calculation using document.documentElement.clientHeight. I was able to remedy this by using screen.height instead.
