Javascript access:

// To SET values ([o] is the target object)
[o].style.right="right value"
// To GET values you must first get the computed style object
// To get that object in IE or Opera:
var cStyle=[o].currentStyle;
// To get that object in Firefox, Chrome or Safari (w3c-type):
var cStyle=window.getComputedStyle([o],null)
// To GET the property value:;
var value=cStyle.right;
/* The returned value is not cross-browser reliable. The value can vary in accuracy and notation, which depends on the browser, whether the value is preset or not and which option that was used to set the value.*/
