推荐使用顺序:
background:imageurl repeat position/size color; //size一定要斜杠,跟在坐标的后面(先有位置,再识别大小)
三个点省略号兼容写法:
/* 超出部分的写法,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;
/* 限制一个块元素显示的文本行数;超出需求以几行的方式显示,超出两行就... */
-webkit-line-clamp: 2;
overflow: hidden;
/*文本溢出隐藏为省略号*/
text-overflow: ellipsis;

flex-grow
设置当父元素的宽度大于所有子元素的宽度的和时(即父元素会有剩余空间),子元素如何分配父元素的剩余空间。 flex-grow
的默认值为0,意思是该元素不索取父元素的剩余空间,如果值大于0,表示索取。值越大,索取的越厉害。
给每一个子元素加上width:0。这样整个父元素的宽度就是剩余宽度,然后进行分配flex-grow,这个时候加上去的宽度就是实实在在的width。
width:0
假如当前宽度特别宽,超出父元素的剩余空间,就不会按照当前的比例分配,所以要设置为0,这样就不会按照没有内容的宽度去分配,而是当前弹性盒模型分配的比例分配
.detail {
flex-grow: 1;
line-height: 60rpx;
