背景

我正在尝试使用Grid CSS,并尝试采用目前已实现缩放的布局

预期的布局 enter image description here

问题: 在桌面上,元素标题应为8列宽,如果我不向element-headerelement添加网格行,则<div class="element">1</div>会填充element-header的旁边。现在,如果我添加grid-rows,我的element将不再自动换行。

当前布局(问题) enter image description here enter image description here

问题 如何修复网格以匹配上面的“预期布局”屏幕截图? 即.element将换行并从第二个网格行开始

代码:

HTML:

<section class="section">
  <div class="container">
    <div class="samba-grid">
      <div class="element-header"><h1>I am a lot of header text that only goes 8 columsn wide</h1></div>
      <div class="element">1</div>
      <div class="element">2</div>
      <div class="element">3</div>
      <div class="element">4</div>     
    </div>
  </div>
</section>

CSS:

.section {
  width: 100%;
  display: block;
  background: red;
  box-sizing: border-box;
  padding: 40px 24px;

  @media screen and (min-width: 600px) and (max-width: 1139px) {
    background: orange;
    padding: 56px 48px;
  }

  @media screen and (min-width: 1140px) {
    padding: 64px 48px;
    background: green;
  }
}

.container {
  margin: 0 auto;
  background: rgba(244,244,244, .25);
  max-width: 599px;

  @media screen and (min-width: 600px) and (max-width: 1139px) {
    max-width: 1039px;
    background: rgba(244,244,244, .25);
  }

  @media screen and (min-width: 1140px) {
    max-width: 1032px;
    background: rgba(244,244,244, .25);
  }
}

.samba-grid {
  display: grid;
  background: inherit;
  width: 100%;
  grid-template-columns: repeat(4, 1fr);
  grid-template-rows: 'auto auto';
  grid-gap: 24px;

  @media screen and (min-width: 600px) and (max-width: 1139px) {
    grid-template-columns: repeat(6, 1fr);
    grid-gap: 48px;
  }

  @media screen and (min-width: 1140px) {
    grid-template-columns: repeat(12, 1fr);
    grid-gap: 48px;
  }
}

h1 {
  font-size: 52px;
}
.element-header {
  grid-row: 1;
  grid-column: span 8; // SET THIS TO "span 12" TO SEE EXPECTED BEHAVIOR
}

.element {
  display: grid; // important to do this.
  background: rgba(0,0,0,.3);
  grid-column: span 3;
  grid-row: 2; // REMOVE THIS TO SEE EXPECTED BEHAVIOR

  @media screen and (min-width: 600px) and (max-width: 1139px) {
    grid-column: span 3;
  }

  @media screen and (min-width: 1140px) {
    grid-column: span 4;
  }
}

将标题从网格容器中取出。使其成为独立的块级元素。

在下面,将仅包含图像的网格容器放置。

答案 1 :(得分:1)

您可以使文本占据整行,然后在内部减小其宽度,从而仅占据所需的宽度。这样,您将阻止第一行,并且任何元素都不能进入那里。

这是一个简化的示例:

.samba-grid {
  display: grid;
  background: inherit;
  width: 100%;
  grid-template-columns: repeat(12, 1fr);
  grid-gap: 24px;
  border:1px solid;
}

.element-header {
  grid-row: 1;
  grid-column: 1/-1;
}
.element-header > h1 {
  /*we take 8 colmuns (without gaps) + 7 gaps*/
  width:calc(8*(100% - 11*24px)/12 + 7*24px);
  background:red;
  margin:0;
}
.samba-grid > span {
  height:50px;
  grid-column: span 2;
  background:green;
}
<div class="samba-grid">
  <div class="element-header">
    <h1>I am a lot of header text that only goes 8 columsn wide</h1>
  </div>
  <span></span>
  <span></span>
  <span></span>
  <span></span>
  <span></span>
  <span></span>
  <span></span>
  <span></span>
</div>

要使其更加动态和易于处理,您可以考虑使用CSS变量:

:root {
  --grid:12;
  --gap:24px;
}

.samba-grid {
  display: grid;
  background: inherit;
  width: 100%;
  grid-template-columns: repeat(var(--grid), 1fr);
  grid-gap: var(--gap);
  border:1px solid;
}

.element-header {
  grid-row: 1;
  grid-column: 1/-1;
  --grid-column:8; /*simply adjust this value to control the column*/
}
.element-header > h1 {
  width:calc(var(--grid-column)*(100% - (var(--grid) - 1)*var(--gap))/var(--grid) + calc(var(--grid-column) - 1)*var(--gap));
  background:red;
  margin:0;
}
.samba-grid > span {
  height:50px;
  grid-column: span 2;
  background:green;
}
<div class="samba-grid">
  <div class="element-header">
    <h1>I am a lot of header text that only goes 8 columsn wide</h1>
  </div>
  <span></span>
  <span></span>
  <span></span>
  <span></span>
  <span></span>
  <span></span>
  <span></span>
  <span></span>
</div>

另一个想法是考虑一个隐藏元素,该元素将占用第一行的剩余空间:

.samba-grid {
  display: grid;
  background: inherit;
  width: 100%;
  grid-template-columns: repeat(12, 1fr);
  grid-gap: 24px;
  border:1px solid;
}

.element-header {
  grid-row: 1;
  grid-column: span 8;
  background:red;
  order:-2;
}

.samba-grid:before {
 content:"";
 order:-1;
 grid-column: span 4;
 background:blue;
 height:2px;
}

.samba-grid > span {
  height:50px;
  grid-column: span 2;
  background:green;
}
<div class="samba-grid">
  <div class="element-header">
    <h1>I am a lot of header text that only goes 8 columsn wide</h1>
  </div>
  <span></span>
  <span></span>
  <span></span>
  <span></span>
  <span></span>
  <span></span>
  <span></span>
  <span></span>
</div>


请注意,设置grid-row: 2并不意味着从第二行开始,而是意味着在第二行之内

答案 2 :(得分:1)

我正在指示.element-header始终跨越可用列的最大数量。对于h1,我在较大的@media查询中添加了一条规则,以保持其正确缩放(12列中的8列)。另外,我评论了.grid-row: 2

.element-header {
  grid-column-start: 1;
  grid-column-end: -1;
}

h1 {
  …  
  @media screen and (min-width: 1140px) {
    width: calc(80% / 120 * 100); /* 8 of 12 columns */
 }

答案 3 :(得分:0)

我将添加一个空元素只是为了填充更高的分辨率。

HTML

<div class="element-header"><h1>I am a lot of header text that only goes 8 columsn wide</h1></div>
<div class='filler'></div>
<div class="element"><img src="https://placebear.com/160/90" alt=""></div>

CSS

.filler {
  display: none;

  @media screen and (min-width: 1140px) {
    grid-column: 9 / span 4;
    display: initial;
  }
}

那样,您可以在该空间上放置一些东西,而自动放置算法不会使用它。

如果分辨率较小,则可以隐藏。
