Padding all-in-one spec

padding

Use this property to specify padding-top, padding-right, padding-bottom, and padding-left.

Property values

This property is used to set each of the four padding properties, which may also be set one by one:

This property expects anywhere from one to four values, with their interpretation as follows:

number of values sides effected
1 value Sets all four sides: top, right, bottom, left
2 values 1st value: top and bottom padding
2nd value: right and left padding
3 values 1st value: top padding
2nd value: right and left padding
3rd value: bottom padding
4 values 1st value: top padding
2nd value: right padding
3rd value: bottom padding
4th value: left padding

Use any of these font-relative typographic units to set the size of the padding:

em em The font-size of the current font
rem relative em The font-size of the <html> element
lh line height The line-height of the current font
rlh relative line height The line-height of the <html> element
cap cap height The nominal height of the current font's capital letters
ex "x" The height of the current font's "x" glyph
ch "0" The advance measure (the width) of the current font's "0" glyph
ic ideograph count The advance measure (the width) of the current font's "水" ideograph

Or use any of these fixed size units which are independent of the current font:

in inch A size equal 96px
px pixels A size equal to 1/96 inch
pt point A size equal 1in/72 = 1.33px
pc pica A size equal 1in/6 = 12pt = 16px
cm centimeter A size equal to 96px/2.54 = 37.8px
mm millimeter A size equal to 96px/25.4 = 3.8px
Q quarter millimeter A size equal to 96px/1016 = 0.94px
