Documentation for arg background_position in `write_xaringan_theme` not clear

[Jessica Burnett]

Can you please clarify in (write_xaringan_theme.rd)[man/write_xaringan_theme.rd] how to specify argument background_position? background-position in theme.css can take two values (%) per argument to specify vertical and horizontal position.

However, when I specify:
r write_xaringan_theme(background-position = c(0,100))
xaringan_themer.css returns with
r background-position: 0;

I am not sure what the solution is, otherwise I would submit a PR.

Here are a few examples from the Background Position section in the css-help vignette.

background_position = "center"
background_position = "top"
background_position = "left"
background_position = "bottom"
background_position = "25% 75%" # X-value (from left) Y-value (from top)
background_position = "bottom 10px right 20px" # 10px from bottom, 20px from right
background_position = "top left 10px" # at top but adjusted left 10px

In general, all arguments to xarignanthemer style functions are CSS values in strings.

I'll leave this issue open so that I remember to clarify this in the documentation.

I've removed the CSS help vignette but I've now documented (in #33) which arguments accept CSS property values and included a link to the MDN Web Docs page describing the syntax for the property values.
