如何将div在网格中的列中移至上方？

问题描述

我是CSS网格的新手，所以我在Codepen中玩CSS，我想知道应该写些什么才能将div向上移动以填充其他div留下的位置。 This is my codepen

awk -v range="4-5" '                                ##Starting awk program from here creating range variable which has range value of positions which we do not want to print in lines.
BEGIN{                                              ##Starting BEGIN section of this program from here.
  split(range,array,"-")                            ##Splitting range variable into array with delimiter of - here.
  start=array[1]                                    ##Assigning 1st element of array to start variable here.
  end=array[2]                                      ##Assigning 2nd element of array to end variable here.
}
{
  print substr($0,1,start-1) substr($0,end+1)       ##Printing sub-string of current line from 1 to till value of start-1 and then printing from end+1 which basically means will skip that range of characters which OP does not want to print.
}
'  Input_file                                       ##Mentioning Input_file name here.

<div class="wrapper">
  <div class="box a">A</div>
  <div class="box b">B</div>
  <div class="box c">C</div>
  <div class="box d">D</div>
  <div class="box e">E</div>
  <div class="box f">F</div>
</div>

如何使框f浮动到其他两个框所在的位置？另外，当框c较大并且我想使框f与框c底部对齐时会发生什么？

解决方法

添加grid-auto-flow: dense;align-items: end;

body {
  margin: 40px;
}

.wrapper {
  display: grid;
  grid-template-columns: 1fr 1fr;
  grid-gap: 10px;
  background-color: #fff;
  color: #444;
  grid-auto-flow: dense;
  align-items: end;
}

.box {
  background-color: #444;
  color: #fff;
  border-radius: 5px;
  padding: 20px;
  font-size: 150%;
}

.d,.e {
  grid-column: 1;
}

.c {
  height: 200px;
}

.f {
  grid-column: 2;
}

<div class="wrapper">
  <div class="box a">A</div>
  <div class="box b">B</div>
  <div class="box c">C</div>
  <div class="box d">D</div>
  <div class="box e">E</div>
  <div class="box f">F</div>
</div>

它是硬编码的，但是您可以使用grid-row-start和grid-row-end来确定元素应该从哪一行开始/结束。

因此，如果将其添加到.f元素，则它应从第二行扩展到第五行。

.f {
  grid-column: 2;
  grid-row-start: 2;
  grid-row-end: 5;
}

,

您可以使用grid-row设置元素的行。在这种情况下， .f 元素就像 grid-row：2/5
