响应式 Flexbox 图像网格

Question

我无法让我的一张图片正确排列。我已经完成了大部分 align vertical-align: middle; 并显示 display: block;options 以删除底部填充。我还将容器设置为width: 100%; 以及图像width: 100%;，因此它应该是响应式的。我不确定是什么导致这张图片有差距。我已将背景颜色设置为黄色，以便显示需要填充的区域。我还注释掉了我尝试但没有成功的所有替代选项。

例子：

 * {
   box-sizing: border-box;
   font-size: 100%;
 }
 
 .container {
   display: flex;
   flex-direction: column;
   max-width: 90%;
   margin: 0 auto;
   background-color: white;
 }
 
 .img__container {
   display: flex;
/*    justify-content: space-between; */
   align-content: center;
   background: yellow;
 }
 
 a .img_item {
   width: 100%;
   height: auto;
   vertical-align: middle;
/*    display: block; */
/*      flex-grow: 1;
  flex-shrink: 0;
  flex-basis: auto; */
 }
 
 .img_item_1,
 .img_item_3,
 .img_item_2 {
   width: 33.33%;
 }
 
 .img_item_4,
 .img_item_5 {
   width: 50%;
 }
 
 .img_item img {
   vertical-align: middle;
/*    display: block; */
   max-width: 100%;

 }

Answer 1

问题是您正在尝试将不同宽高比的图像放入相同大小的框中（我说图像是因为它还显示您的前两个图像在底部有 1 个像素的间隙。）

您的选择是：

在 CMS 端将所有图像裁剪为相同大小。

或

将您的图片附加为内嵌背景图片，并在您的 CSS 文件中将 background-size 设置为 cover 并将 background-position 设置为 center center。您还需要调整其他一些事情。如果您对这种方法感兴趣，请在 cmets 中告诉我，我可以使用 sn-p 编辑我的答案。

背景图片（为简洁起见，我只做了一张）：

* {
   box-sizing: border-box;
   font-size: 100%;
 }
 
 .container {
   display: flex;
   flex-direction: column;
   max-width: 90%;
   margin: 0 auto;
   background-color: white;
 }
 
 .img__container {
   display: flex;
   align-content: center;
   background: yellow;
 }

 .img_item {
   background-size: cover;
   background-position: center center;
 }
 
 .img_item_4,
 .img_item_5 {
   width: 50%;
 }
 
 .img_item img {
   vertical-align: middle;
   max-width: 100%;

 }
