CSS 网格中的网格区域布局不正确

Question

我想使用 CSS 网格系统制作我的网站，但它似乎无法正常工作。这是我的代码：

.grid {
  display: grid;
  grid-template-columns: 1fr 1fr;
  grid-template-rows: 1fr 1fr;
  grid-template-areas: "logo faq" "about-us";
}

.logo {
  background-color: blue;
  grid-area: logo;
}

.faq {
  background-color: red;
  grid-area: faq;
}

.aboutUs {
  background-color: cyan;
  grid-area: about-us;
}

<div class="grid">
  <div class="logo">
    LOGO
  </div>
  <div class="faq">
    FAq
  </div>
  <div class="aboutUs">
    About-us
  </div>
</div>

Answer 1

如果这样：

是你想要的结果，那么你只是犯了一个小错误。

您在此处将网格设置为 2 x 2 正方形：

  grid-template-columns: 1fr 1fr;
  grid-template-rows: 1fr 1fr;

但您并没有填写所有 space。

  grid-template-areas: "logo faq", "about-us";

那行代码说的是 "In the top two squares put logo and faq respectively. In the bottom two rows put about-us"，这会导致错误。如果你想让一个grid-area填满整个space那么你需要声明它两次。因此上面的行变成：

  grid-template-areas: "logo faq", "about-us about-us";

.grid {
  display: grid;
  grid-template-columns: 1fr 1fr;
  grid-template-rows: 1fr 1fr;
  grid-template-areas: "logo faq", "about-us";
}

.logo {
  background-color: blue;
  grid-area: logo;
}

.faq {
  background-color: red;
  grid-area: faq;
}

.aboutUs {
  background-color: cyan;
  grid-area: about-us;
}

<div class="grid">
  <div class="logo">
    LOGO
  </div>
  <div class="faq">
    FAq
  </div>
  <div class="aboutUs">
    About-us
  </div>
</div>

Answer 2

当使用 grid-template-areas 属性时，字符串值必须具有相同的列数。

.grid {
  display: grid;
  grid-template-columns: 1fr 1fr;
  grid-template-rows: 1fr 1fr;
  grid-template-areas: "logo faq" "about-us about-us";
}

.logo {
  background-color: blue;
  grid-area: logo;
}

.faq {
  background-color: red;
  grid-area: faq;
}

.aboutUs {
  background-color: cyan;
  grid-area: about-us;
}

<div class="grid">
  <div class="logo">
    LOGO
  </div>
  <div class="faq">
    FAq
  </div>
  <div class="aboutUs">
    About-us
  </div>
</div>

您可以使用句点或不间断的句点行来表示空单元格 (spec reference)。

.grid {
  display: grid;
  grid-template-columns: 1fr 1fr;
  grid-template-rows: 1fr 1fr;
  grid-template-areas: "logo faq" " ... about-us";
}

.logo {
  background-color: blue;
  grid-area: logo;
}

.faq {
  background-color: red;
  grid-area: faq;
}

.aboutUs {
  background-color: cyan;
  grid-area: about-us;
}

<div class="grid">
  <div class="logo">
    LOGO
  </div>
  <div class="faq">
    FAq
  </div>
  <div class="aboutUs">
    About-us
  </div>
</div>

来自网格规范：

7.3. Named Areas: the grid-template-areas property

All strings must have the same number of columns, or else the declaration is invalid.

If a named grid area spans multiple grid cells, but those cells do not form a single filled-in rectangle, the declaration is invalid.

Non-rectangular or disconnected regions may be permitted in a future version of this module.

注意：如规范所述，除了列数相等外，网格区域也必须是矩形 ()。
