Question

我正在尝试将span对齐到div的右边，范围在按钮内。

我已经设法完成上述操作，但是在将标头垂直对齐的同时将它保持在左侧时遇到了问题。

.spec-li>li>span {
  padding: 5px 0 0 0;
}

.spec-label {
  display: block;
  float: left;
  width: 50%;
  font-weight: 700;
  font-size: 12px;
}

.spec-value {
  display: block;
  float: right;
  width: 50%;
  text-align: right;
  font-size: 12px;
}

.card-header-spec {
  display: flex;
  justify-content: space-between
}

.card-spec-button-font-size {
  font-size: 30px
}

.spec-card {
  border-width: 0;
  border-top-width: 1px;
  background-color: none;
}

Answer 1

在CSS中，要垂直对齐，请在align-items: center内添加card-header-spec。

下面是经过修改的CSS

.spec-li>li>span {
  padding: 5px 0 0 0;
}

.spec-label {
  display: block;
  float: left;
  width: 50%;
  font-weight: 700;
  font-size: 12px;
}

.spec-value {
  display: block;
  float: right;
  width: 50%;
  text-align: right;
  font-size: 12px;
}

.card-header-spec {
  display: flex;
  justify-content: space-between;
  align-items: center;
}

.card-spec-button-font-size {
  font-size: 30px
}

.spec-card {
  border-width: 0;
  border-top-width: 1px;
  background-color: none;
}

Answer 2

如果要将h5垂直居中对齐。做这个。

.card-header-spec {
    display: flex;
    justify-content: space-between;
}

如您在代码前面所看到的，h5的父级的card-header-spac为flex。在bootstrap-4中，您使用align-items-center将flex元素的内容在其中心垂直对齐。

    .spec-li>li>span {
      padding: 5px 0 0 0;
    }

    .spec-label {
      display: block;
      float: left;
      width: 50%;
      font-weight: 700;
      font-size: 12px;
    }

    .spec-value {
      display: block;
      float: right;
      width: 50%;
      text-align: right;
      font-size: 12px;
    }

    .card-header-spec {
      display: flex;
      justify-content: space-between
    }

    .card-spec-button-font-size {
      font-size: 30px
    }

    .spec-card {
      border-width: 0;
      border-top-width: 1px;
      background-color: none;
    }

如果要使用自定义CSS，请对align-items: center类使用card-header-spec。

.card-header-spec {
    display: flex;
    justify-content: space-between;
    align-items: center;
}
