Question

我想在左侧创建一个带有我名字的标题，并使用flexbox在右侧创建一个“about”“portfolio”“contact”的导航器。

我在我的flexbox容器中使用in-range，但项目不合适，他们留在左边，我不知道为什么。

我可以使用各种justify-content: flex-end;，但标题保持不变。

我想知道我是如何将“Roger Anderson”这个名字留在左边，然后是“关于，投资组合，联系”。

justify-content

Answer 1

你有这个：

.nav {
  margin-right: auto;  
}

而是使用它：

.nav {
  margin-left: auto;  
}

Flex auto页边距消耗了边距方向的所有可用空间。

因此，当您在导航菜单上设置margin-right: auto时，会消耗右侧的所有可用空间，将菜单固定在左侧。

但如果您使用margin-left: auto，则会消耗左侧的所有可用空间，将菜单推离徽标并将其固定在右侧。

以下是一个更完整的解释：

In CSS Flexbox, why are there no "justify-items" and "justify-self" properties?

justify-content无效的原因有两个：

Flex auto页边距优先于关键字对齐属性（例如justify-content和align-items）。如果设置了auto页边距，则会获得第一个镜头并消耗该行上的所有可用空间。 justify-content排在第二位，但没有剩余空间，所以它无能为力。


8.1. Aligning with auto margins

在通过justify-content和align-self进行对齐之前   正空闲空间分配到auto边距   尺寸。

如果可用空间分配到auto边距，则对齐   由于边距，属性在该维度中不起作用   屈服后会偷走剩下的所有可用空间。
即使没有auto页边距，justify-content正在运行，也无法正常工作，因为您将值设置为flex-end。这会将所有项目固定在右侧。您需要使用space-between或space-around。

Answer 2

     .primary-header {
        display: flex;
        flex-direction: row;
        justify-content: space-between;
      }

Answer 3

Justify-content：flex-end;将证明右侧的标题和列表项。你想使用justify-content：space-between;代替。（A Complete Guide to Flexbox）
您可以使用flexbox将列表项放在彼此旁边。只需添加display：flex;到.nav ul。
删除display：inline-block;来自li元素和margin-right：auto;来自.nav。就个人而言，我更喜欢纯粹通过flexbox属性来解决对齐问题。

示例：

Dim myClassList as New Lsit(Of MyClass)

使用flexbox将我的徽标设置在左侧，将导航菜单设置在右侧
