marquee provides a small set of helpers for constructing the needed styles.
relative() specifies a numeric value as relative to the value of the parent
style by a certain factor, e.g. a font size of relative(0.5) would give a
style a font size half of it's parent. em() specify a numeric value as
relative to the font size of the current style. If the font size is 12, and
indent is set to em(2), then the indent will be equivalent to 24. rem()
works like em() but rather than using the font size of the current style it
uses the font size of the root style (which is the body element). trbl()
helps you construct styles that refers to sides of a rectangle (margin,
padding, and border size). The function names refers to the order of the
arguments (top, right, bottom, left). skip_inherit() tells the style
inheritance to ignore this value and look for the value one above in the
stack. marquee_bullets is just a character vector with 6 sensible bullet
glyphs for unordered lists.
Usage
relative(x)
em(x)
rem(x)
trbl(top = NULL, right = top, bottom = top, left = right)
skip_inherit(x)
marquee_bulletsArguments
- x
A decimal number. If a vector is provided only the first element will be used
- top, right, bottom, left
Values for the sides of the rectangles. Either numbers or modifiers (relative, em, or rem)
Examples
relative(0.35)
#> relative(0.35)
em(2)
#> em(2)
rem(1.2)
#> rem(1.2)
# Argument default means it recycles like CSS if fewer values are specified
trbl(6, em(1.5))
#> A marquee trbl
#> top: 6
#> right: em(1.5)
#> bottom: 6
#> left: em(1.5)
skip_inherit("sans")
#> sans (no inheritance)
