Helpers for defining styles

Description

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_bullets

Arguments

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)

Format

An object of class character of length 6.

Value

Objects of the relevant class

Examples

relative(0.35)

em(2)

rem(1.2)

# Argument default means it recycles like CSS if fewer values are specified
trbl(6, em(1.5))

skip_inherit("sans")
