I'm trying to create a textarea that looks exactly like a div.
However, on iOS there's 3 pixels coming from somewhere that I can't remove.
Here's my code:
<!doctype html>
<title>Textarea test</title>
<style>
textarea, div
{
background: yellow;
font: 13px arial;
border: 0;
padding: 0;
border-radius: 0;
margin: 0;
-webkit-appearance: none;
}
</style>
<div>test</div>
<hr>
<textarea>test</textarea>
This is rendered like so (I've zoomed in):

As the screenshot shows, there's 3 pixels before the text that I want to get rid of. As far as I can see it's not the margin/padding or border.
This happens on my iPhone and iPad, both running iOS 4.3. And to be clear; those 3 extra pixels don't show up on Safari/Firefox/Chrome on my desktop. Or my brother's Windows Phone, for that matter.
EDIT 2011-08-10:
I've just tested this on a <input type=text> and the same "padding" thing appears, except that it's 1 pixel instead of 3.
