/ Hugo, will by default, just replace the extension of the source
/ to .css, e.g. "scss/main.scss" becomes "scss/main.css". You can
/ control this by setting this, e.g. "styles/main.css" will create
/ a Resource with that as a base for RelPermalink etc.
TargetPath string
/ Hugo automatically adds the entry directories (where the main.scss lives)
/ for project and themes to the list of include paths sent to LibSASS.
/ Any paths set in this setting will be appended. Note that these will be
/ treated as relative to the working dir, i.e. no include paths outside the
/ project/themes.
IncludePaths []string
/ Default is nested.
/ One of nested, expanded, compact, compressed.
OutputStyle string
/ Precision of floating point math.
Precision int
/ When enabled, Hugo will generate a source map.
