html - 网格布局无法对齐

Question

我正在尝试实现这一点，我希望 nav 和 header 标签填充左侧。

html {
    width: 100%;
    overflow: hidden;
}
    
body {
   display: grid;
   grid-template-rows: 1fr 5fr 1fr;
   grid-template-columns: 2fr 5fr 3fr;
   grid-template-areas: 
       "header header"
       "nav main"
       "footer footer";
}
    
header {
    background: yellowgreen;
}
    
nav {
    background: lightblue;
}
    
main {
    background: aliceblue;
}
    
footer {
    background: lightgoldenrodyellow;
}

<header>Banner</header>
<nav>Navigation</nav>
<main>Main content</main>
<footer>Footer</footer>

Answer 1

你可以这样试试

.item1 { grid-area: header; }
.item2 { grid-area: menu; }
.item3 { grid-area: main; }
.item5 { grid-area: footer; }

.grid-container {
  display: grid;
  grid-template-areas:
  'header main main main  '
  'menu main main main  '
  'menu footer footer footer  ';
  grid-gap: 10px;
  background-color: #2196F3;
  padding: 10px;
}

.grid-container > div {
  background-color: rgba(255, 255, 255, 0.8);
  text-align: center;
  padding: 20px 0;
  font-size: 30px;
}

<div class="grid-container">
  <div class="item1">Header</div>
  <div class="item2">Menu</div>
  <div class="item3">Main</div>  
  <div class="item5">Footer</div>
</div>
