javascript:

 $(".diag_options p label").on("click",function(){         if($(this).hasclass("none_opt")){             $('.diag_options p label').removeclass("check");             $(this).addclass("check");         }         else if($(this).hasclass("check")){             $(this).removeclass("check");         }         else{             $('.diag_options ul p label').removeclass("check");             $(this).addclass("check");         } }); 

css:

input[type="radio"], input[type="checkbox"] {     line-height: normal;     margin: 4px 0 0; } input[type="checkbox"], input[type="radio"] {     box-sizing: border-box;     padding: 0; } input, button, select, textarea {     font-family: inherit;     font-size: inherit;     line-height: inherit; } .diag_options p {     float: left;     margin: 1%;     width: 14.66%; }  .diag_options p label {     border: 1px solid #ccc;     color: #999;     display: block;     font-family: roboto-regular;     font-size: 0.8rem;     font-weight: 400;     height: auto;     line-height: 1;     margin: 0;     min-height: 125px;     padding: 44px 10px 0;     position: relative;     text-align: center; } .pap_answer label {     -moz-user-select: none; } .diag_options p label::before {     content: "";     display: none; } .check {     background: #f98586 none repeat scroll 0 0;     border: 1px solid #fff !important;     color: #fff !important; } .check::after {     background: rgba(0, 0, 0, 0) url("/assets/paps_images/sprite_icon.svg") no-repeat scroll -110px 0 / auto 100%;     content: "";     height: 22px;     position: absolute;     right: 0;     top: 0;     width: 22px; } 

if rely on checkbox being checked, instead of clicking label, avoid such problems

$(".diag_options p input").on("change",function(){     $(this).next().toggleclass('check', this.checked); });
