这是我从未见过的非常特殊的情况。第一张图片是我从Adobe XD制作的模型,第二张图片是我的Google Chrome浏览器的网站的屏幕截图,显示了浏览器如何解释网格。
如您所见,我有两个导航元素:“ sub nav”,它提供组织链接;和“主导航”,它提供站点链接。 CSS id / class命名约定如下:
#header__main-nav 和#header__sub-nav是导航HTML元素; #main-nav__container 和#sub-nav__container是ul HTML元素; .main-nav__item和.sub-nav__item是li元素;和 .main-nav__link和.sub-nav__link是定位标记。
我创建了一个包含十列两行的网格。徽标被故意从其父“ header”元素中“溢出”,占据了整个第一列,而其他八列则被分为两行,每行都有一个nav元素。但是,从网格轮廓中可以看到,这没有发生。徽标跨越第一列的一行,与sub-nav共享,而main-nav位于徽标下方的第二行。
模型:
突出显示子导航,显示第一行大小:
主导航突出显示,显示第二行大小,但不包括“网格区域:徽标”:

我尝试更具体地说明我的列大小并添加第三行,该行仅由第一列中的徽标占据。结果相同-不变。

答案 0 :(得分:2)
您需要将grid-area: logo
从img#header__logo
移到a
父级。
您对Grid的工作方式有误解,或者根据看到的方式出现编码错误。
这是您的网格HTML:
有四个网格项。
这是容器的CSS:
header#grid__header {
height: 9vw;
z-index: 1;
margin: 0;
display: grid;
grid-template-columns: calc(15vw + 1em) 9fr;
grid-template-rows: 1fr 2fr;
grid-template-areas: "logo sub-nav"
"logo main-nav";
}
看起来不错。徽标设置为两行。
正确定义了sub-nav
网格区域:
nav#header__sub-nav {
grid-area: sub-nav;
height: auto;
width: calc(75vw - 1em);
height: auto;
margin: 0;
}
正确定义了main-nav
网格区域:
nav#header__main-nav {
grid-area: main-nav;
width: calc(75vw - 1em);
height: auto;
}
但是,缺少徽标网格区域。
实际上,您已经在网格项的子项上定义了logo
网格区域:
由于将网格区域应用于网格项目的子项,因此它是out of scope,因此该规则将被忽略。将规则移到父规则,网格容器可以在其中看到规则。
