i have these bootstrap classes , want concatenate each 1 li, there best option add li before each class? mean, way group bootstrap classes , concatenate li.

.col-xs-1, .col-sm-1, .col-md-1, .col-lg-1, .col-xs-2, .col-sm-2, .col-md-2, .col-lg-2, .col-xs-3, .col-sm-3, .col-md-3, .col-lg-3, .col-xs-4, .col-sm-4, .col-md-4, .col-lg-4, .col-xs-5, .col-sm-5, .col-md-5, .col-lg-5, .col-xs-6, .col-sm-6, .col-md-6, .col-lg-6, .col-xs-7, .col-sm-7, .col-md-7, .col-lg-7, .col-xs-8, .col-sm-8, .col-md-8, .col-lg-8, .col-xs-9, .col-sm-9, .col-md-9, .col-lg-9, .col-xs-10, .col-sm-10, .col-md-10, .col-lg-10, .col-xs-11, .col-sm-11, .col-md-11, .col-lg-11, .col-xs-12, .col-sm-12, .col-md-12, .col-lg-12

in case want these four: li .col-xs-4 li .col-sm-4 li .col-md-4 li .col-lg-4 prefer generally.

i think you're looking this.

li[class*='col-'], li[class^='col-'] {   ... } 

remember not include space between li , [class*='col-']. combination of 2 selectors above done in order prevent classes foo-col-1 selected.
