Template Variables
================

The following table shows the template variables, their default values
in the standard `xaringan` theme, the primary element to which the
property is applied, and a brief description of the template variable.

For example, `background_color` by default sets the `background-color`
CSS property of the `.remark-slide-content` class to `#FFF`.

Use this table to find the template variable you would like to modify.
You can also use this table to find the CSS class or element associated
with a particular template item.

Note that themes, like `mono_accent()`, have additional parameters, but
with any theme function you can override the theme by directly setting
the arguments below when calling the theme function. For example, to use
`mono_accent()` with a different slide background color, you can call
`mono_accent(background_color =
"#abc123")`.
