npm install wintersmith-autoprefixer-sass -g
wintersmith-autoprefixer-sass to your plugins in the wintersmith config
This plugin only supports Wintersmith 2.0 or higher and requires wintersmith-sass 0.3.*
wintersmith-autoprefixer-sass requires the sass gem to be installed as it uses the sass cmd to compile the css files Please see sass for installation details
This plugin extends (through some admittedly dodgy way) the original wintersmith-sass plugin to provide a chained build step through autoprefixer.
If you wish to use autoprefixer with scss files in Wintersmith, simply include this plugin (and not wintersmith-sass as it is provided automatically). It uses the order of plugin loads to initiate wintersmith-sass and use the global plugins reference to extend the SassPlugin class.
If you want to have sass output a compressed file, simply add a sass variable
$compressed: true; to each .scss or .sass file you want compressed.
If you want to have sass compile with Compass imports available, simply add a sass variable
$compass: true; to each .scss or .sass file you want compile with Compass.
As per sass guidelines, all non partial .scss files will be parsed into a compiled css file and output. Partials, scss files beginning with _ (underscore) will be ignored unless imported.
