Define

You can use the define method to define global variables. This can make things clearer and more efficient. Note that these variables are referred to by their bare (unquoted) names in the rule method.

Linne$new()$
define(
theme = "blue",
font_size = 20
)$rule( sel_tag("h1"), color = theme, fontSize = font_size )$
rule(
sel_tag("p"),
color = theme
)

In the example above were I to later want to change the theme color it would have to be changed in only one place.

Import

There is a method called import which corresponds to the CSS at-rule of the same name. It allows importing other CSS files. It is often used for fonts.

For instance to use Google fonts visit the website, Click a font you would like to use from the main grid then (see print screen below) click “Select this style,” this should open a drawer on the right from which you can copy the URL and CSS rule to use that font.

The Robot font (print screen above) can thus be applied like so.

Linne$new()$
)
