移动混合开发之android文件管理新建文件和删除文件
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
今天經過一天超過8小時的實踐，有很多CSS上的細節需要注意：
1，
/*注意是對before的操作*/ .content ul li .icon-check-empty:before{display: block;/*webFont設置其width和height時無效,只有設置font-size*//*width: 3rem;*//*height: 3rem;*/font-size: 1.5rem;position: absolute;top:0;left: 0;bottom: 0;padding: .75rem; }
2.選擇器的優先級
/*估計這個優先級沒有 .down a{}的高,所以根本沒執行a.btn{} > .down a{} > .down a.btn{} */ /*.down a.btn{*//*background: lavender;*//*border: solid 1px grey;*//*border-radius: 5px;*//*padding: 5px;*/ /*}*/ .opeator a{/*使用felx:1讓內容平均分布*/flex:1;-webkit-box-flex: 1;/*把webFont當作字體處理,字體居中*/text-align: center;text-decoration: none;display: block;}
3.動畫的設置
需要設置一個初始狀態和結束狀態，
.opeator{position: absolute;bottom: 0;left: 0;right: 0;height: 3rem;/*容器使用 display:felx屬性*/display:flex;display: -webkit-flex; /* *//*注意是transform*/transition:-webkit-transform 0.3s ease-in;transform: translateY(0) translateZ(0); }.opeator.down {transform: translateY(3rem) translateZ(0); }
全部代碼：
