You can specify a size value and the unit of measurement for the font-size property of the <body> tag in a DITA2Go-generated CSS file. Or, you can direct DITA2Go not to include a <body> tag entry in the CSS file; then you can substitute your own entry, in the project configuration file. Use one or the other method to specify a font size other than the default:
To specify font size and unit of measurement for the <body> tag:
[CSS] ; CssBodyFontSize = value for body {font-size: }, used as base for all ; em and ex sizes, and for font-size and line-height %, default 10. CssBodyFontSize=10 ; CssBodyFontUnit = units for body {font-size: }, default 0: ; 0=pt, 1=pc, 2=in, 3=cm, 4=mm, 7=px (pixels). CssBodyFontUnit=0
CssBodyFontSize determines how values of relative measures em, ex , and % are computed for other CSS style properties. For example, 1.5em in a style property equals 1.5 times the value in pt (or in another non-relative unit) of the <body> tag font-size property.
CssBodyFontUnit should be an absolute unit of measurement rather than a relative unit.
To prevent DITA2Go from automatically including a style entry for the <body> tag in a DITA2Go-generated CSS file:
[CSS] ; CssBodyFontTag = Yes (default, writes body { font-size:) or No CssBodyFontTag=No
To specify the default font size yourself, provide a custom entry in macro section [CSSStartMacro]. For example:
[CSSStartMacro] body { font-size: 11pt; margin: 0 0 0 0 }
