Synopsis
Read/Write
The font size of the element. The font size can be set in several
ways. A collection of constants (xx-small
,
x-small
, small
,
medium
, large
,
x-large
, xx-large
) defines what
are known as absolute sizes. In truth, these are absolute as far as a
single browser in a single operating system goes, since the reference
point for these sizes varies with browser and operating system. But
they do let the author have confidence that one element set to
large
is rendered larger than
medium
.
Another collection of constants (larger
,
smaller
) is known as relative sizes. Because the
font-size attribute is inherited from the parent element, these
relative sizes are applied to the parent element to determine the
font size of the current element. It is up to the browser to
determine exactly how much larger or smaller the font size is, and a
lot depends on how the parent element’s font size is set. If it
is set with one of the absolute sizes (large
, for
example), a child’s font size of larger
means the font is rendered in the browser’s
x-large
size. The increments are not as clear-cut
when the parent font size is set with a length or percentage.
If you elect to use a length value for the
fontSize
property, choose a unit that makes the
most sense for fonts, such as points (pt
) or ems
(em
). The latter bases its calculation on the size
of the parent element’s font size. Finally, you can set
fontSize
to a percentage, which is calculated based on the size ...
