  show_title = FALSE, relative_to = NULL)

Arguments

site_yml	path to the `_site.yml` file.
logo_img	vector containing the path to the logo file(s).
show_title	boolean. If `TRUE`, the title will be shown next to the logo.
relative_to	relative path where main site files are located (`file.path(path, yaml_link)`): _e.g._ if navbar is used in a subfolder, adjust path to "..".
