Flexbox 图片库响应问题答案

【问题标题】：Flexbox image gallery responsiveness issueFlexbox 图片库响应问题
【发布时间】：2021-09-13 16:00:46
【问题描述】：

我正在使用 flexbox 制作响应式图片库。为此，我的html结构如下：

<main class="image-container">
    <div class="image-wrapper">
        <img src="#">
    </div>
    <div class="image-wrapper">
        <img src="#">
    </div>
    ....so on many 
</main>

下面是我的css sn-p：

.image-container {
        width: 90%;
       height: 2480px;
        margin: 20px auto 0px;
        background: rgba(209, 217, 223, 0.705);
        display: flex;
        flex-wrap: wrap;
        flex-direction: column;
        justify-content: space-evenly;
        align-content: space-evenly;
        position: relative;            
   }
  .image-wrapper {
       width: 30%;
       margin: 0px auto 8px;
       flex-shrink: 0;
   }
    img{
        width: 100%;  
        height: 100%;
   }

现在为了使这个响应，我必须使用媒体查询。假设我的笔记本电脑屏幕宽度为 1280 像素。我试图得到3 columns of images into 2 column at 760px breakpoint。问题是当我尝试减小屏幕尺寸时，突然从最后一列生成了 1180px 的尴尬空间。 我明白了，我有 2480px 的刚性容器高度。正因为如此，我的身高保持不变，width is 90% 图像越来越小，第三列图像被添加到其他列中。我已经尽力了，所以欢迎任何建议。有什么可以在 html 或 css 中做的吗？如果您无法理解该场景，我很抱歉。

【解决方案1】：

对于此类问题，您应该将媒体查询代码添加到您的 css 文件中。如果你想在大屏幕上显示 3 张图片，你应该删除 flex-direction: row 来自 .image-container 以便 image-wrappers 可以并排。当屏幕缩小时，它们应该换行。我在此处添加 codepen 链接，以便您查看它。如果您还有其他问题。我可以回答他们。 https://codepen.io/atesirem/pen/ExmPgdP

.image-container {
        width: 90%;
        margin: 20px auto 0px auto;
        padding:20px;
        background: rgba(209, 217, 223, 0.705);
        display: flex;
        flex-wrap: wrap;
        flex-direction: row;
        justify-content: center;
        align-content: space-evenly;
        position: relative;            
   }

  .image-wrapper {
       width: 30%;
       margin: 0px auto 8px;
       flex-shrink: 0;
   }
    img{
        width: 100%;  
        height: auto;
   }

@media screen and (max-width:991px) {
  .image-container {
        flex-wrap: wrap;
   }
}
@media screen and (max-width:768px) {
  .image-container {
                
   }
  .image-wrapper {
       width: 45%;
   }
}
@media screen and (max-width:500px) {
  .image-container {
        flex-direction: column;
                 
   }
  .image-wrapper {
       width: 90%;
   }
}

【讨论】：

非常感谢您的帮助。我现在可以对场景进行排序，在哪里更好地使用哪些属性。我使用flex-direction: column 的原因是我有不同高度的图像，我不想让它们都具有相同的大小以正确对齐。这是我的代码笔的链接。我在顶部使用了您的 css，下面对我的 css 进行了评论。也检查我的。 codepen.io/Biebk/pen/KKmKpVy
嗨，我检查了你的代码，我想我可以清楚地理解你想要做什么（我希望）。我认为您想要 3 列，并且图像将开始从上到下列出自己，以及何时进入下一列。我将在下面的答案中添加我所做的。

【解决方案2】：

我做了什么来使它变得更好。希望能给你一点帮助。

        .image-container {
            width: 90%;
            height: 2800px;
            min-height:fit-content;
          scroll-behavior:smooth;
          overflow:scroll;
          max-width:1280px;
            margin: 20px auto 20px auto;
            padding: 20px 0px;
            background: rgba(209, 217, 223, 0.705);
            display: flex;
            flex-wrap: wrap;
            flex-direction: column;
            justify-content: flex-start;
            align-content: space-evenly;
            position: relative;

            
       }
 @media screen and (max-width:500px) {
  .image-container {
        flex-direction: column;
        max-height: inherit;
                 
   }
  .image-wrapper {
       width: 90%;
   }
}
@media screen and (max-width:500px) {
  .image-wrapper {
       width: 90%;
   }
}

是的，这样更好也更容易理解
@ates_irem，重要的是您帮助了解我做错了什么。谢谢！
