A demo of autoprefixer breaking sourcemaps.

== Demo ==

The Autoprefixer turnes out to reduce sourceMap quality.

Steps to reproduce:

1. Installation

git clone https://github.com/aslushnikov/autoprefixer-breaks-sourcemap
cd autoprefixer-breaks-sourcemap
npm install .

2. Build style.scss with autoprefixer

gulp sass

output sourcemap

Notice, how the "red" sass variable is not mapped anywhere.

3. Build style.scss without autoprefixer (via commenting out autoprefixer pipe in gulpfile.js)

gulp sass

output sourcemap

Notice, how "red" sass variable is now matched to CSS property value.
