Points are an absolute length-based unit (
<length>
) equal to 1/72 of an
inch. Points can be useful when setting type sizes for print and similar
media where physical measurements may be stressed. On screen and
mobile media, points are approximated based on the resolution of the
display and the system settings, and working with
px
or
em
units can lead
to more consistent results.
.column1 { width:
30%
; } /* 30% of the containing block
width */
p { line-height:
140%
; } /* 140% of the font-size of the
element */
p.note { font-size:
90%
; } /* 90% of the parent's
font-size */
Percentage-based units (
<percentage>
) are relative to another measure-
ment. Percentages can be greater than 100 percent. Which measurement
the value relates to is defined on a case-by-case basis; the previous code
lines show some examples.
