css实战细节

1. 超出部分显示...

overflow: hidden;
white-space: nowrap;
text-overflow: ellipsis;

2. 滚轮

• 显示

  overflow-x: hidden;
  overflow-y: scroll;

• 自定义

::-webkit-scrollbar{
  width: 24px;
}//整个滚轮
::-webkit-scrollbar-track{
  background: #0C1C58;
  border: 1px solid #112459;
}//轨道
::-webkit-scrollbar-thumb{
  opacity: 0.7;
  background: #3499DF;
}//滑轮

3. flex

  justify-content: space-around;//副轴
  align-items: flex-start;//主轴

4. float

• 清除浮动

.clearfix:after {
  content: '';
  display: block;
  clear: both
}

5. 行内文字垂直居中

vertical-align: middle;
line-height: 父元素的height;
