问:如何让box1和box3对齐父div的顶部boxContainer?
#boxContainerContainer {
  background: #fdd;
  text-align: center;
}
#boxContainer {
  display: inline-block;
  border: thick dotted #060;
  margin: 0px auto 10px auto;
  text-align: left;
}
#box1 {
  width: 50px;
  height: 50px;
  background: #999;
  display: inline-block;
}
#box2 {
  width: 50px;
  height: 100px;
  background: #999;
  display: inline-block;
}
#box3 {
  width: 50px;
  height: 50px;
  background: #999;
  display: inline-block;
}
非常感谢...
