ruby-asciidoctor-pdf-1.5.3/docs/theming-guide.adoc-70-* An underscore (`_`) may be used in place of a hyphen (`-`) in all property names (so you may use `font_family` or `font-family`).
ruby-asciidoctor-pdf-1.5.3/docs/theming-guide.adoc:71:* An underscore (`_`) may be used in place of a hyphen (`-`) in all variable names (so you may use `$base_font_family` or `$base-font-family`).
ruby-asciidoctor-pdf-1.5.3/docs/theming-guide.adoc-72-* Instead of separate properties for font weight and font style, the theme language combines these settings in the `font-style` property (allowed values: `normal`, `bold`, `italic` and `bold_italic`).
##############################################
ruby-asciidoctor-pdf-1.5.3/docs/theming-guide.adoc-248-To save you from having to type the same value in your theme over and over, or to allow you to base one value on another, the theme language supports variables.
ruby-asciidoctor-pdf-1.5.3/docs/theming-guide.adoc:249:Variables consist of the key name preceded by a dollar sign (`$`) (e.g., `$base-font-size`).
ruby-asciidoctor-pdf-1.5.3/docs/theming-guide.adoc-250-Any qualified key that has already been defined can be referenced in the value of another key.

ruby-asciidoctor-pdf-1.5.3/docs/theming-guide.adoc:265:the variable `$base-font-color` will be available for use in subsequent lines and will resolve to `#333333`.

ruby-asciidoctor-pdf-1.5.3/docs/theming-guide.adoc-267-Let's say you want to make the font color of the sidebar title the same as the heading font color.
ruby-asciidoctor-pdf-1.5.3/docs/theming-guide.adoc:268:Just assign the value `$heading-font-color` to the `$sidebar-title-font-color`.

ruby-asciidoctor-pdf-1.5.3/docs/theming-guide.adoc-1380-It's used as an intermediate property for computing the `base-line-height` from the base font size and the desired line height size.
ruby-asciidoctor-pdf-1.5.3/docs/theming-guide.adoc:1381:For instance, if you set `base-line-height-length`, you can use `$base-line-height-length / $base-font-size` to set the value of `base-line-height`.
ruby-asciidoctor-pdf-1.5.3/docs/theming-guide.adoc-1382-You don't have to go about it this way in your own theme.
