举荐应用程序：

background:imageurl repeat position/size color; //size肯定要斜杠，跟在坐标的前面（先有地位，再辨认大小）

三个点省略号兼容写法：

/* 超出局部的写法，有点兼容性问题，所以要这么写。加webkit *//*定义为盒子显示*/display: -webkit-box; /*定义为竖向编排显示*/-webkit-box-orient: vertical;/* 限度一个块元素显示的文本行数;超出需要以几行的形式显示，超出两行就... */-webkit-line-clamp: 2; overflow: hidden;/*文本溢出暗藏为省略号*/text-overflow: ellipsis;
