表格 tr 隔行换色

table tr:nth-child(odd){background:#FFF;}
table tr:nth-child(even){background:#F4F4F4;}

transition 渐隐和背景过度

.div {
    transition: background-color 0.5s ease-out,opacity 0.5s;
    -webkit-transition: background-color 0.5s ease-out,opacity 0.5s;
    -moz-transition: background-color 0.5s ease-out,opacity 0.5s;
    -o-transition: background-color 0.5s ease-out,opacity 0.5s;
}
.div2 {
    transition: opacity 0.5s;
    -webkit-transition: opacity 2s;
    -moz-transition: opacity 0.5s;
    -o-transition: opacity 0.5s;
}

图片按照偏移坐标加载

.fa {
    background:url(full-image.png) no-repeat 0px -100px;
    width: 75px;
    height: 75px;
}

.fa a{
    display:block;
    line-height:75px;
    text-decoration:none;
    text-indent:-200px; /*放一个比较大的值,让a的标题不显示出来*/
    overflow:hidden;
}
