我正在尝试创建一个可重复使用的框，其中包含一个删除和编辑按钮。但是无论我怎么尝试，我都无法让它水平居中。

.inputBox .content {
  flex: 2;
}

.inputBox .icon {
  flex: 1;
  max-width: 50px;
}

Answer 1

应用 display:flex , align-items:center , justify-content:center 到 .icon class...

...或在 .icon

中使用 d-flex align-items-center justify-content-center bootstrap 预定义的 classes

.inputBox .content {
  flex: 2;
}

.inputBox .icon {
  flex: 1;
  max-width: 50px;
  display: flex;
  align-items: center;
  justify-content: center;
}
