Double clearfix on .container and .row

Created by: rafciok

Why is that doubled?

.container:before, .container:after { display: table; content: " "; }

.container:after { clear: both; }

.container:before, .container:after { display: table; content: " "; }

.container:after { clear: both; }

.row:before, .row:after { display: table; content: " "; }

.row:after { clear: both; }

.row:before, .row:after { display: table; content: " "; }

.row:after { clear: both; }
