The CSS reference
"padding-left" - css property (v. css 1)
- Sets the left padding of an element.
- Initial value: 0
- The property is not inherited
- HTML usage: All elements except table-row-group, table-header-group, table-footer-group, table-row, table-column-group and table-column
-
Browsers that support the padding-left - property :
How width, height, margin, border and padding properties relates to each other:
• 'margin-top'
• 'margin-bottom'
• 'margin-left'
'margin-right'
•
• 'border-top-width'
• 'border-bottom-width'
• 'border-left-width'
'border-right-width'
•
-
The total element width is calculated as:
'margin-left' + 'border-left-width' + 'padding-left' + 'width' + 'padding-right' + 'border-right-width' + 'margin-right' -
The total element height is calculated as:
'margin-top' + 'border-top-width' + 'padding-top' + 'height' + 'padding-bottom' + 'border-bottom-width' + 'margin-bottom'

Javascript access:
// To SET values ([o] is the target object)
[o].style.paddingLeft="padding-left 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.paddingLeft;
// IE and Opera will return a value in units as used with a Set.
// Firefox will return a calculated float value in pixel (px).
// Chrome or Safari will return a calculated int value in pixel (px).
