[xwuji]

hi,
my css code is
.card-small-sku { width: 100%; height: 2.2rem; margin: .3rem auto; display: -webkit-box; display: -webkit-flex; display: flex; -webkit-box-align: center; -moz-align-items: center; -webkit-align-items: center; align-items: center; position: relative }
after webpack with using this plugin,it becomes likes this:
.card-small-sku { width: 100%; height: 2.2rem; margin: .3rem auto; display: flex; -moz-align-items: center; align-items: center; position: relative }
this code lost some prefix that want to fit some browsers
what should i do , change some plugin params?

The plugin uses cssnano as a cssProcessor by default. You can control the cssnano options via the cssProcessorOptions option.

    new OptimizeCssAssetsPlugin({
      cssProcessorOptions: { safe: true, discardComments: { removeAll: true } }
    })

Take a look at cssnano options (you probably want to control the autoprefixer options).
