Bootstrap 3: pull-right for col-lg only

Answer 1

This is what i am using . change @screen-md-max for other sizes

/* Pull left in lg resolutions */
@media (min-width: @screen-md-max) {
    .pull-xs-right {
        float: right !important;
    }
    .pull-xs-left {
        float: left !important;
    }

    .radio-inline.pull-xs-left  + .radio-inline.pull-xs-left ,
    .checkbox-inline.pull-xs-left  + .checkbox-inline.pull-xs-left  {
        margin-left: 0;
    }
    .radio-inline.pull-xs-left, .checkbox-inline.pull-xs-left{
        margin-right: 10px;
    }
}
