CSS 网格项目未填充单元格

Question

When I say it doesnt fill the cell this is what I mean 我创建的网格有问题。放置在网格中的项目不会填满单元格。所有项目似乎都正确定位并且响应迅速，但它们实际上不会填满单元格。抱歉，如果这很明显，我是 HTML 和 CSS 的新手。我认为我的代码没有完全优化并且可以更短，但这就是我发现的方式 :')。这里是HTML代码

.about-grid {
  display: grid;
  height: 100vh;
  grid-template-columns: 1fr 1fr 1fr 1fr;
  grid-template-rows: 0.2fr 1.5fr 1.2fr 0.8fr;
  grid-template-areas: "nav nav nav nav" "sidebar main main main" "sidebar content1 content2 content3" "sidebar footer footer footer";
  grid-gap: 0.2rem;
  font-weight: 800;
  text-transform: uppercase;
  font-size: 12px;
  color: #004d40;
  text-align: center;
}

.about-grid nav {
  background: #a7ffeb;
  grid-area: nav;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid main {
  background: #84ffff;
  grid-area: main;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid #sidebar {
  background: #18ffff;
  grid-area: sidebar;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid #content1 {
  background: #6fffd2;
  grid-area: content1;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid #content2 {
  background: #64ffda;
  grid-area: content2;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid #content3 {
  background: #73ffba;
  grid-area: content3;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid footer {
  background: #1de9b6;
  grid-area: footer;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid a {
  text-align: center;
  display: block;
  font-family: inherit;
  text-decoration: none;
  font-weight: bold;
  margin: 1rem;
}

@media only screen and (max-width: 550px) {
  .about-grid {
    grid-template-columns: 1fr;
    grid-template-rows: 0.4fr 0.4fr 2.2fr 1.2fr 1.2fr 1.2fr 1fr;
    grid-template-areas: "nav" "sidebar" "main" "content1" "content2" "content3" "footer";
  }
}

<main class="about-bg">
  <div class="about-grid">
    <nav>Navbar</nav>
    <main>Main</main>
    <div id="sidebar">Sidebar</div>
    <div id="content1">Content1</div>

您的意思是去除单元格之间的小边距吗？如果是，则设置 grid-gap: 0 即可：

演示：

.about-grid
{
  display: grid;
  height: 100vh;
  grid-template-columns: 1fr 1fr 1fr 1fr;
  grid-template-rows: 0.2fr 1.5fr 1.2fr 0.8fr;
  grid-template-areas:
    "nav nav nav nav"
    "sidebar main main main"
    "sidebar content1 content2 content3"
    "sidebar footer footer footer";
    
  /*The only thing I changed, grid-gap*/
  grid-gap: 0;
  
  font-weight: 800;
  text-transform: uppercase;
  font-size: 12px;
  color: #004d40;
  text-align: center;
}

.about-grid nav {
  background: #a7ffeb;
  grid-area: nav;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid main {
  background: #84ffff;
  grid-area: main;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid #sidebar {
  background: #18ffff;
  grid-area: sidebar;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid #content1 {
  background: #6fffd2;
  grid-area: content1;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid #content2 {
  background: #64ffda;
  grid-area: content2;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid #content3 {
  background: #73ffba;
  grid-area: content3;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid footer {
  background: #1de9b6;
  grid-area: footer;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid a {
  text-align: center;
  display: block;
  font-family: inherit;
  text-decoration: none;
  font-weight: bold;
  margin: 1rem;
}

@media only screen and (max-width: 550px) {
  .about-grid {
    grid-template-columns: 1fr;
    grid-template-rows: 0.4fr 0.4fr 2.2fr 1.2fr 1.2fr 1.2fr 1fr;
    grid-template-areas:
      "nav"
      "sidebar"
      "main"
      "content1"
      "content2"
      "content3"
      "footer";
  }
}

 <main class="about-bg">
    <div class="about-grid">
        <nav>Navbar</nav>
        <main>Main</main>
        <div id="sidebar">Sidebar</div>
        <div id="content1">Content1</div>
        <div id="content2">Content2</div>
        <div id="content3">Content3</div>
        <footer>Footer</footer>
     </div>
     
</main>

我不太明白你的问题，但我在你的代码中看到了一个不同的问题。当您用大文本填充所有单元格时，您的网格将超出屏幕。也许你的意思是这个问题。您需要为 .about-grid 选择器指定 overflow-wrap: anywhere 规则。现在单元格的内容将取决于单元格本身的宽度。

检查 overflow-wrap: anywhere 的工作原理。运行这个片段并从 .about-grid 选择器中删除 overflow-wrap: anywhere 规则，你应该明白我在说什么。

body {
    box-sizing: border-box;
    margin: 0;
    padding: 0;
}

.about-grid {
  display: grid;
  height: 100vh;
  grid-template-columns: 1fr 1fr 1fr 1fr;
  grid-template-rows: 0.2fr 1.5fr 1.2fr 0.8fr;
  grid-template-areas: "nav nav nav nav" "sidebar main main main" "sidebar content1 content2 content3" "sidebar footer footer footer";
  grid-gap: 0.2rem;
  font-weight: 800;
  text-transform: uppercase;
  font-size: 12px;
  color: #004d40;
  text-align: center;
  overflow-wrap: anywhere; /*add this it*/
}

.about-grid nav {
  background: #a7ffeb;
  grid-area: nav;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid main {
  background: #84ffff;
  grid-area: main;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid #sidebar {
  background: #18ffff;
  grid-area: sidebar;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid #content1 {
  background: #6fffd2;
  grid-area: content1;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid #content2 {
  background: #64ffda;
  grid-area: content2;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid #content3 {
  background: #73ffba;
  grid-area: content3;
  border-radius: var(--main-radius);
  padding-top: var(--main-padding);
}

.about-grid footer {
  background: #1de9b6;
  grid-area: footer;
  border-radius: var(--main-radius);

.about-grid a {

    grid-template-areas: "nav" "sidebar" "main" "content1" "content2" "content3" "footer";
  }
}
