如何在 flex 显示中使文本直接在 h4 下对齐？

Question

我正在尝试使 p 标签在 h4 下对齐并带有轻微缩进，但即使添加了 float:left; or text-align:left; 之类的 css 属性，它也不会移动到下面。下图显示了正在发生的事情 测试漂浮在 FreeCodeCamp 之上，但我需要它在它之下。下面是我的代码的 sn-p，你可以运行它。

Answer 1

h4 和 p 不应该是 flex-child，因为默认情况下 flex-direction 是 row，您可以将它们包装在一起以正常运行：

示例：

.navbar-custom {
  background: #2C3E50;
  font-family: "Montserrat", "Helvetica Neue", Helvetica, Arial, sans-serif;
  text-transform: uppercase;
  font-weight: 700;
  border: none;
}

.navbar-custom .navbar-brand {
  color: white;
}

.navbar-custom .navbar-brand:hover,
.navbar-custom .navbar-brand:focus,
.navbar-custom .navbar-brand:active,
.navbar-custom .navbar-brand.active {
  color: white;
}

.navbar-custom .navbar-nav {
  letter-spacing: 1px;
}

.navbar-custom .navbar-nav li a {
  color: white;
}

.navbar-custom .navbar-nav li a:hover {
  color: #18BC9C;
}

.navbar-custom .navbar-nav li a:focus,
.navbar-custom .navbar-nav li a:active {
  color: white;
}

.navbar-custom .navbar-nav li.active a {
  color: white;
  background: #18BC9C;
}

.navbar-custom .navbar-nav li.active a:hover,
.navbar-custom .navbar-nav li.active a:focus,
.navbar-custom .navbar-nav li.active a:active {
  color: white;
  background: #18BC9C;
}

.navbar-custom .navbar-toggle {
  color: white;
  text-transform: uppercase;
  font-size: 10px;
  border-color: white;
}

.navbar-custom .navbar-toggle:hover,
.navbar-custom .navbar-toggle:focus {
  background-color: #18BC9C;
  color: white;
  border-color: #18BC9C;
}

@media (min-width: 768px) {
  .navbar-custom {
    padding: 25px 0;
    -webkit-transition: padding 0.3s;
    -moz-transition: padding 0.3s;
    transition: padding 0.3s;
  }
  .navbar-custom .navbar-brand {
    font-size: 2em;
    -webkit-transition: all 0.3s;
    -moz-transition: all 0.3s;
    transition: all 0.3s;
  }
  .navbar-custom.affix {
    padding: 10px 0;
  }
  .navbar-custom.affix .navbar-brand {

flex-direction:column 可以应用，但需要固定的 height 并允许 wrapping 。常规的 block 行为包装 h4 和 p 在我自己看来会很好
