我想为我的某个应用程序使用后台更新，对后台获取的逻辑有点困惑 - 我必须在何时何地调用 .btn-group{
margin-top: 20px;
margin-left: 20px;
}
#left, #middle, #right{
height: 25px;
}
.button-content{
}
.button-icon{
}
.button-text{
vertical-align:middle;
}
.button-text i{
font-size: 12px; /* Change of icon-size doesn´t apply */
}
#left, #middle, #right {
height: auto;
}
.button-icon {
display: inline-block;
vertical-align: middle;
line-height: 0;
}
方法？网上的教程建议在 <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">

</div>上调用它，但是在预定的后台提取尚未开始之前用户手动启动应用程序会发生什么？它是否会被取消并重新安排，或者是否为该应用程序安排了另外一次获取操作？请指教！提前感谢您的评论和答案！
