中心响应图像

Question

我的图片不会以 margin: 0 auto; 或 padding: 0 auto; 居中如果我在它周围的 <div> 中执行 text-align: center;，它也不起作用。我认为这是因为图像具有响应性。那么如何让这些图像居中呢？

@media only screen and (min-width: 1001px) {
  .gallerij {
    max-width: 825px;
    margin: 20px auto;
    padding: 0 10px 30px 200px;
  }
}

.gallerij h1 {
  margin-left: 10px;
}

.gallerij div.img {
  border: 1px solid #ccc;
  padding: 0;
  margin-top: 10px;
  background-color: rgba(211, 211, 211, 0.30);
}

.gallerij div.img:hover {
  border: 1px solid #000000;
}

.gallerij div.img img {
  display: block;
  width: auto;
  max-width: 100%;
  height: 200px;
  padding: 3px;
  margin-left: auto;
  margin-right: auto;
}

.gallerij div.desc {
  padding: 15px;
  text-align: center;
}

.gallerij * {
  box-sizing: border-box;
}

.responsive {
  padding: 0 6px;
  float: left;
  width: 24.9999%;
  max-width: 200px;
}

@media only screen and (max-width: 700px) {
  .responsive {
    width: 49.99999%;
  }
}

@media only screen and (max-width: 500px) {
  .responsive {
    width: 100%;
  }
}

.gallerij .clearfix:after {
  content: "";
  display: table;
  clear: both;
  margin-bottom: 30px;
}

HTML 看起来那么长，因为我必须做更多的图片，这样你才能明白我的意思。当您单击 "full page" 时，它们将是彼此相邻的 4 张图像，在这个小图像中（可能）是 3 张，我不知道您是否可以将其缩小，但随后它将变成 2 张图像，最后是 1 张。当它为 3 和 4 时它居中，但当它为 2 或 1 时它不再居中。如果您能看到它没有集中在代码段上，我会知道，所以我会粘贴一些打印屏幕来显示它。

2 张图片并排：

1 张图片：

唯一的问题是它们没有居中，我找不到如何做到这一点。

您需要更多代码或信息吗？

Answer 1

这应该有效：

.gallerij {
    width: 420px;
    margin: 0 auto;
}

Answer 2

将您的图片包裹在一个包罗万象的 div 中，并以 flexbox 居中。

或者，从您的项目中删除 float:left，使它们成为 display:inline-block，然后将它们包裹在 div 和 text-align:center 中。

Flexbox 示例：

<div style="
    display: flex;
    flex-flow: row wrap;
    justify-content: center;
">
    <div class="responsive">
        <div class="img">
            <a href="#">
                <img src="img/ERD_Easy/img2.jpg" alt="" class="article-img">
            </a>
            <div class="desc">Artikel naam + kleine bescrijving</div>
        </div>
    </div>
    ...
</div>

没有 flexbox 解决方案：

<div style="text-align:center;">
    <div class="responsive" style="float:none;display:inline-block;">
        <div class="img">
            <a href="#">
                <img src="img/ERD_Easy/img2.jpg" alt="" class="article-img">
            </a>
            <div class="desc">Artikel naam + kleine bescrijving</div>
        </div>
    </div>
    ...
</div>

我想这可能是您想要的？确保移除浮动以将图像从浮动到左侧重置。还添加了边距：0 auto；（或者 text-align 以图像容器为中心）无论你想做什么。

@media only screen and (min-width: 1001px) {
  .gallerij {
    max-width: 825px;
    margin: 20px auto;

.gallerij h1 {
  margin-left: 10px;
