.checkbox-indigo[type="checkbox"] + label:before{ border: 2px solid indigo; background: transparent; } .checkbox-indigo[type="checkbox"]:checked + label:before{ border: 2px solid transparent; border-bottom: 2px solid indigo; border-right: 2px solid indigo; background: transparent; } .checkbox-indigo.filled-in[type="checkbox"] + label:after{ border: 2px solid indigo; background: transparent; } .checkbox-indigo.filled-in[type="checkbox"]:checked + label:after{ background: indigo; } .checkbox-indigo.filled-in[type="checkbox"]:checked + label:before{ border-top: 2px solid transparent; border-left: 2px solid transparent; border-right: 2px solid #fff; border-bottom: 2px solid #fff; }
