targeting specific browsers with css: 
for IE, conditional comments for specific versions:
<!--[if lt IE 7]> <style type="text/css"...... <![endif]-->

for Firefox:
@-moz-document url-prefix(){
	selector{rule:value;}
}

for Webkit/Safari:
@media screen and (-webkit-min-device-pixel-ratio:0) {
	.selector{rule:value;}
}

for opera:
@media all and (-webkit-min-device-pixel-ratio:10000), not all and (-webkit-min-device-pixel-ratio:0){
	#selector{rule:value;}
}
SAFARI

borders on text-input fields: give the field an position:absolute and clip it by 2px, clip: rect(2px <width-2>px 18px 2px); eg: 


<input type="text" value="TESTING" style="border:0;padding:0;
	clip: rect(2px 78px 18px 2px);position:absolute;width:80px;background:#cf0" />

Abstract: CSS position: attribute and positioning.

CSS rules: 
postion: absolute;
position: relative;
position: static;

# = some valid value
top: #;
left: #;
bottom: #;
right: #;

absolute: absolute postion with respect to the next block-level parent with a postion rule. if there is none then the body ( root of the document).
NOTE: this pulls the element out of the flow of elements, so elements which follow flow as though this element does not exist: you will see the elements which follow flow under the absolutely positioned block, and wrapping blocks will collapse

relative: relative with respect to block-level siblings or (generally) the position on the document where this element comes to live naturally based on the available space.

typographic extensions
	oraphans widows line-break page-break-[after, before, inside]
potentially replaced with keep rule based on
element type (block/inline) and syntax: line, word, paragraph, page, strict, japanese, etc

we need clipping types other than rect

type needs to be rotatable

kerning table
input string + tracking (or assign default)

....parse string - into divs by line - measure - adjust strings for more desirable rag/div width [tolerance range]
