Let's use custom rules, untill https://github.com/acss-io/atomizer/issues/308
Install from npm
npm install atomizer-emmet-compat --save-dev
Modify your atomizer rules
// import
var compat = require('atomizer-emmet-compat');
// define your custom rules
var rules = [];
// merge arrays and export
module.exports = rules.concat(compat);
