Details

The general usage of CSS styling is

<span style = "color: red; border: 1px">Text</span>

The text color can be specified by `color`, the border of element by `border`, and etc.

Basic styles like color, border, background work properly and mostly consistently in modern web browsers. However, some style properties may not work consistently in different browsers.

Examples

style(color = "red")
#> [1] "color: red"
style(color = "red", "font-weight" = "bold")
#> [1] "color: red; font-weight: bold"
style("background-color" = "gray", "border-radius" = "4px")
#> [1] "background-color: gray; border-radius: 4px"
style("padding-right" = "2px")
#> [1] "padding-right: 2px"

  mpg = formatter("span",
    style = x ~ style(color = ifelse(x > median(x), "red", NA)))))
