css - bootstrap 4 中的多行居中导航栏元素

Question

我有一个导航栏，当只有单行元素时它工作正常:

<div class="collapse navbar-collapse" id="navbarSupportedContent">
            <ul class="navbar-nav ml-auto">

                <li class="nav-item">
                    <a class="nav-link" href="#">FAQ</a>
                </li>

                <li class="nav-item">
                    <a class="nav-link profile" href="#">
                        <div class="profile-info">
                            <span class="name">Артём</span>
                        </div>
                    </a>
                </li>
            </ul>
        </div>

但是当 item 是多行时，其他 item 会失去垂直居中对齐并改为顶部对齐:

<div class="collapse navbar-collapse" id="navbarSupportedContent">
            <ul class="navbar-nav ml-auto">

                <li class="nav-item">
                    <a class="nav-link" href="#">FAQ</a>
                </li>

                <li class="nav-item">
                    <a class="nav-link profile" href="#">
                        <div class="profile-info">
                            <span class="name">Артём</span>
                            <span class="balance">31337 ₽</span>
                        </div>
                    </a>
                </li>
            </ul>
        </div>

我的 SASS 代码:

#site-header {
  background: #2d3840;
  border-bottom: solid 1px #20272d;
  height: 83px;

  .navbar-brand {
    color: white;
  }

  .nav-item {

    &:not(:first-child) {
      margin-left: 25px;
    }

    &:not(:last-child) {
      margin-right: 25px;
    }

    // General link
    a.nav-link {
      color: white;
      font-size: 16px;
      text-align: center;

      @include transition(0.5s);
      &:hover {
        @include transition(0.3s);
        color: $color-accent;
      }

      &.active {
        padding: 6px 21px 6px 21px;
        background: $color-accent;
        border-radius: 17.5px;
        box-shadow: 0 2px 10px 0 rgba(90, 175, 238, 0.6);

        &:hover {
          color: white;
          box-shadow: none;
        }
      }

      // Profile
      &.profile {
        .profile-info {
          display: inline-block;

          .name {
            display: block;
            font-weight: bold;
          }

          .balance {
            display: block;
            font-size: 16px;
            font-weight: bold;
            color: $color-accent;
          }
        }
      }
    }

  }
}

期望:

那么，多行元素如何居中呢？

Answer 1

删除 profile-info 并将这些类用于 a 标记。

1. d-flex - 使其成为 flex
2. flex-column - 将其 flex-direction 属性更改为 column
3. text-right - 将其 inline 子级对齐在它的右侧

<li class="nav-item">
  <a class="nav-link d-flex flex-column text-right" href="#">
    <span class="name">Артём</span>
    <span class="balance">31337 ₽</span>
  </a>
</li>

要在列表的中心垂直对齐其他 items，请对每个 li 元素使用 align-self-center .

<li class="nav-item  align-self-center">
  <a class="nav-link" href="#">FAQ</a>
</li>
