获取网格行以覆盖网格模板行

Question

我问这是我自己的教育，如果这是一种不好的做法，请随意这么说。

我希望通过为每个元素设置单独的网格行设置来覆盖元素#one #two #three和#four的父属性grid-template-rows: 100px 100px 100px 100px。

元素#one和#two像这样设置它们时，正如我期望的那样响应：

#one{
     grid-row: 1/ span 4 ; 
}

#two{
     grid-row: 1/ span 4 ; 
}

但是，当我尝试对#three和#four应用类似的设置时，却没有得到我期望的结果。我希望#three和#four的高度与#one和#two完全相同。相反，它们会飞到页面的一侧。

我希望它显示与#one和#two类似的元素。它不起作用：

#three{
     grid-row: 2/ span 4 ; 
}


#four{
     grid-row: 2/ span 4 ; 
}

我想知道如何解决此问题以及正确的单个值以设置#three和#four来覆盖网格模板行，如所述。

[您需要重写grid auto-placement algorithm，当未明确定义网格区域时，该区域将计算渲染网格区域的“正确”位置。

您正在定义行。只需定义列即可。

.container {
  display: grid;
  grid-template-columns: 1fr 2fr;
  grid-template-rows: 100px 100px 100px 100px 100px 100px;
  grid-gap: 10px;
}

#one {
  grid-row: 1 / span 4;
  grid-column: 1;
}

#two {
  grid-row: 1 / span 4;
  grid-column: 2;
}

#three {
  grid-row: 2 / span 4;
  grid-column: 1;
}

#four {
  grid-row: 2 / span 4;
  grid-column: 2;
}

  font-family: Helvetica;
  font-size: 1em;
  color: white;
  text-align: center;
}

img {
  display: block;
  margin: 20px 20px;
  margin-left: auto;
  margin-right: auto;
  border-radius: 50%;
  border-width: 5px;
  border-style: solid;
  border-color: rgb(141, 110, 99);
  max-width: 50%;
  height: auto;
}

.container div:nth-child(even) {
  background-color: orange;
}

.container div:nth-child(odd) {
  background-color: purple;
}

<div class="container">
  <div id="one">1
    <div class="content-container"></div>
  </div>
  <div id="two">2
    <div class="content-container">text</div>
  </div>
  <div id="three">3
    <div class="content-container">text</div>
  </div>
  <div id="four">4
    <div class="content-container">text</div>
  </div>
  <div id="five">5
    <div class="content-container">text</div>
  </div>
  <div id="six">6
    <div class="content-container">text</div>
  </div>
</div>

您会注意到#one和#three以及#two和#four看起来不一样。实际上，它们是。

问题是，您已将#three和#four设置为在网格行第2行开始扩展。

Well，#one和#two设置为从网格行第1行开始，跨4行。因此它们是重叠的。您需要在网格行第5行开始#three和#four。

.container {
  display: grid;
  grid-template-columns: 1fr 2fr;
  grid-template-rows: 100px 100px 100px 100px 100px 100px;
  grid-gap: 10px;
  grid-auto-rows: 100px; /* added to accommodate more rows */
}

#one {
  grid-row: 1 / span 4;
  grid-column: 1;
}

#two {
  grid-row: 1 / span 4;
  grid-column: 2;
}

#three {
  grid-row: 5 / span 4;
  grid-column: 1;
}

#four {
  grid-row: 5 / span 4;
  grid-column: 2;
}

  margin-left: auto;
