Minify css with clean-css.
This is just a simple gulp plugin, which means it's nothing more than a thin wrapper around
clean-css. If it looks like you are having CSS related issues, please contact clean-css. Only create a new issue if it looks like you're having a problem with the plugin itself.
|Description||Minify css with clean-css, including optional caching.|

Source maps can be generated by using gulp-sourcemaps:
var gulp = require'gulp';var minifyCSS = require'gulp-minify-css';var sourcemaps = require'gulp-sourcemaps';gulptask'minify-css'return gulpsrc'./src/*.css'pipesourcemapsinitpipeminifyCSSpipesourcemapswritepipegulpdest'dist';;
When minifying (and import inlining) files with existing source map, be aware clean-css doesn't yet support source maps with inline source (
sourcesContent property).. See #397. As such ensure that incoming source maps have properly set
soureces values to map back to the original source files.
