Duplicate code

[InsiteFX]

Is there a reason that there's alot of duplicate code in the css source file?

SEE BELOW:

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

.container:after { clear: both; }

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

.row:after { clear: both; }

.form-horizontal .form-group:before, .form-horizontal .form-group:after { display: table; content: " "; }

.form-horizontal .form-group:after { clear: both; }

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