.accordion { 
    margin-bottom: 20px; 
} 
.accordion-group { 
    margin-bottom: 2px; 
    /*border: 1px solid #e5e5e5; 
    -webkit-border-radius: 4px; 
    -moz-border-radius: 4px; 
    border-radius: 4px;*/ 
} 
.accordion-heading { 
    border-bottom: 0; 
    background-color:#cccccc; 
} 
.accordion-heading .accordion-toggle { 
    display: block; 
    padding: 2px 4px; 
    text-decoration:none; 
    /*background-color:#e52b27;*/

手風琴有一個已知的bug與IE：https://github.com/twitter/bootstrap/issues/4745

您需要將Bootstrap更新爲最新版本。
