Size and Color Values

There are about a dozen MathML properties whose values can be expressed in a wide variety of formats. In the property dialogs, these values are set by text fields where you can type any valid value. In many cases, the values are either sizes or colors. The format for these two kinds of values are explained below.

Size Values

A number of MathML properties involve sizes, such as "font size". In the Editor, sizes can be specified in two formats:

Format	Example
number with unit	1 cm, .8 em
percentage	120% (of normal size)

The list of valid MathML units is shown below:

Unit identifier	Unit description
em	em (font-relative unit traditionally used for horizontal lengths -- width of an 'M')
ex	ex (font-relative unit traditionally used for vertical lengths -- height of an 'x')
px	pixels, or pixel size of the current display
in	inches (1 inch = 2.54 centimeters)
cm	centimeters
mm	millimeters
pt	points (1 point = 1/72 inch)
pc	picas (1 pica = 12 points)

Color Values

MathML color properties accept normal CSS color values. The following table summarizes the valid formats for specifying color values:

Format	Example
3-digit hexadecimal RGB values	#00f (blue), #000 (black)
6-digit hexadecimal RRGGBB values	#00ff00 (green), #999999 (medium gray)
color keyword	'aqua', 'black', 'blue', 'fuchsia', 'gray', 'green', 'lime', 'maroon', 'navy', 'olive', 'purple', 'red', 'silver', 'teal', 'white', or 'yellow'
