Question

我是一名学生想要了解css网格。如何更改特定div列或行的大小而不更改它们，并将图片等元素插入到网格中？

我在这里尝试过：https://codepen.io/lukeheald/pen/bYQNgj

如果我想要调整它的特定div，它会改变所有这些的高度。

body{
        font-family: 'Anton', sans-serif;
        margin: 0;
    }
    
    /* Main sidebar style, dark background and transition.*/
    
    #sidebar{
        background: black;
        width: 200px;
        height: 100%;
        display: block;
        position: absolute;
        left: -200px;
        top: 0px;
        transition: left 0.3s linear;
    }
    
    /* Sidebar visibile transition and position*/
    
    #sidebar.visible{
        left: 0px;
        transition: left 0.3s linear;
    }
    
    /* ul list styles*/
    
    ul{
        margin: 0px;
        padding: 0px;
    }
    
    /* list styles*/
    
     ul li{
        list-style: none;
    }

        margin-bottom: 5px;
        display: block;

    /* changing 2 line to have smaller width than top.*/
    
    #sidebar-btn span:nth-child(2){
        width: 75%;
    }
    
    /* changing third line to be smaller than 2nd line */
    
    #sidebar-btn span:nth-child(3){

Answer 1

更改行的高度或列的宽度后，该更改将在整行中发生。因此它会自然地影响行/列上的所有网格项。

解决问题的一种方法是创建一个包含许多小行/列的网格。然后让您的项目跨越足够的行/列以达到所需的长度。

在下面的示例中，有一个包含两列和12行的网格容器。但它看起来只有三排。我使用span关键字来设置单个项目的高度。（您不必使用span。Grid provides multiple methods for sizing and positioning items.）

＆＃13;

article {
  display: grid;
  grid-template-columns: 1fr 1fr;
  grid-template-rows: repeat(12, 1fr);
  grid-row-gap: 5px;  
  height: 75vh;
}

section:nth-child(1) { grid-column-start: 1;  grid-row: 1 / span 3; }
section:nth-child(2) { grid-column-start: 2;  grid-row: 1 / span 4; }
section:nth-child(3) { grid-column-start: 1;  grid-row: 5 / span 2; }
section:nth-child(4) { grid-column-start: 2;  grid-row: 5 / span 3; }
section:nth-child(5) { grid-column-start: 1;  grid-row: 9 / span 4; }
section:nth-child(6) { grid-column-start: 2;  grid-row: 9 / span 2; }

/* for illustration only */
section:nth-child(odd)  { background-color: lightgreen; }
section:nth-child(even) { background-color: orangered;  }
article                 { border: 1px solid gray;       }

以下是使用示例笔更改网格容器的示例。这是你正在寻找的吗？

只更改一个网格容器而不影响其他网格容器： https://codepen.io/suefeng/pen/XzyXVb

.image1 {
    grid-area: image1;
    background-color: blue;
    width: 200px;
    height: 200px;
}

更改列宽，使一个更窄，一个更宽： https://codepen.io/suefeng/pen/vWQLpe

@media screen and (min-width: 736px)
{
    .grid {
      display: grid;
      grid-template-columns: .5fr 1.5fr;
      grid-template-rows: 1fr 1fr 1fr 1fr 1fr 1fr;
      grid-template-areas: 
          "title title"
          "image1 text1"
          "image2 text2"
          "image3 text3"
          "image4 text4"
          "footer footer";
    }
}

将每一行更改为不同的高度： https://codepen.io/suefeng/pen/jaQWjN

@media screen and (min-width: 736px)
{
    .grid {
      display: grid;
      grid-template-columns: .5fr 1.5fr;
      grid-template-rows: .5fr 1fr 1.5fr 2fr 2.5fr 3fr;
      grid-template-areas: 
          "title title"
          "image1 text1"
          "image2 text2"
          "image3 text3"
          "image4 text4"
          "footer footer";
    }
}
