文字一直在我图片的右边

Question

我的问题

我正在尝试为每个图像制作一个在其下面带有标题的照相馆。但是我遇到的问题是标题一直浮动在图像旁边。作为参考，请参见此screenshot。

CSS代码段

@media only screen and (max-width: 600px) {
  .boxGallery {
    margin-left: 50%;
    margin-right: 50;
  }
}

.GalleryBox {
  display: block;
  padding-left: 100px;
  padding-right: 100px;
  width: 100%;
}

.boxGallery {
  display: block;
  margin-left: auto;
  margin-right: auto;
  width: 80%;
}

div.gallery {
  margin: 5px;
  float: left;
  width: 250px;
}

div.gallery img {
  width: 250px;
  height: 190px;
}

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

<div class="boxGallery">
  <div class="gallery">
    <img src="https://placeimg.com/640/480/any">
  </div>

  <div class="gallery">
    <img src="https://placeimg.com/640/480/any">
  </div>
</div>

<div class="desc">
  <p>Auvergne, Frankrijk 2018</p>
</div>

<div class="boxGallery">
  <div class="gallery">
    <img src="https://placeimg.com/640/480/any">
  </div>

  <div class="gallery">
    <img src="https://placeimg.com/640/480/any">
  </div>
</div>

有关如何解决此问题的任何帮助。

Answer 1

您已经<script type="text/x-mathjax-config"> MathJax.Hub.Config({ tex2jax: { inlineMath: [['$','$'], ['\\(','\\)']] }, "HTML-CSS": { linebreaks: { automatic: true } }, SVG: { linebreaks: { automatic: true } } }); </script> 浮动了，所以它弹出了正常的HTML流程，并且父级不知道子元素的实际高度。您的.gallery需要“ clear-fix”来清除浮动元素的高度：

.boxGallery

    visibility: hidden;

    content: "";
    clear: both;

}

  .boxGallery {
    margin-left: 50%;
    margin-right: 50;
  }
}

.boxGallery {
  display: block;
  margin-left: auto;
  margin-right: auto;
  width: 80%;
}

.boxGallery:after {
  display: block;
  content: "";
  clear: both;
  position: relative;
}

div.gallery {
  margin: 5px;
  float: left;
  width: 250px;
}

div.gallery img {
  width: 250px;
  height: 190px;
}

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

因为您正在浮动.boxGallery中的元素，所以父项目失去了尺寸（因为它不再考虑浮动内容了）。由于子项是浮动的，因此标题将定位为浮动项的“填充符”。

您可以通过所谓的clearfix解决此问题。这些天，一个clearfix很简单：

.clearfixme::after {
    content: '';
    clear: both;
    display: table;
}

@media only screen and (max-width: 600px) {
  .boxGallery {
    margin-left: auto;
    margin-right: auto;
  }
}

.GalleryBox {
  display: block;
  padding-left: 100px;
  padding-right: 100px;
  width: 100%;
}

.boxGallery {
  display: block;
  margin-left: auto;
  margin-right: auto;
  width: 80%;
}

.boxGallery::after {
content: '';
clear: both;
display: table;
}

div.gallery {
  margin: 5px;
  float: left;
  width: 250px;
}

div.gallery img {
  width: 250px;
  height: 190px;
}

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

<div class="boxGallery">
  <div class="gallery">
    <img src="https://placeimg.com/640/480/any">
  </div>

  <div class="gallery">
    <img src="https://placeimg.com/640/480/any">
  </div>
</div>

<div class="desc">
  <p>Auvergne, Frankrijk 2018</p>
</div>

<div class="boxGallery">
  <div class="gallery">
    <img src="https://placeimg.com/640/480/any">
  </div>

  <div class="gallery">
    <img src="https://placeimg.com/640/480/any">
  </div>
</div>

或者，我将为此使用flex。我会怎么做：

.boxGallery {
  display: flex;
  align-items: center;
  justify-content: center;
  flex-wrap: wrap;
}

.gallery {
  min-width: 120px;
  width: 25%;
  margin: 12px;
}

.gallery img {
  width: 100%;
  height: auto;
}

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

<div class="boxGallery">
  <div class="gallery">
    <img src="https://placeimg.com/640/480/any">
  </div>

  <div class="gallery">
    <img src="https://placeimg.com/640/480/any">
  </div>
</div>

<div class="desc">
  <p>Auvergne, Frankrijk 2018</p>
</div>

<div class="boxGallery">
  <div class="gallery">
    <img src="https://placeimg.com/640/480/any">
  </div>
  <div class="gallery">
    <img src="https://placeimg.com/640/480/any">
  </div>
  <div class="gallery">
    <img src="https://placeimg.com/640/480/any">
  </div>
</div>

Answer 3

由于您浮动了图像，因此图像被从正常流程中删除，并且.boxGallery元素的行为就好像它们不再存在了，只承认.desc元素。要解决此问题，您需要添加一个明确的修复程序，如下所示：

.boxGallery::after {
  content: "";
  display: table;
  clear: both;
}

要使图像居中，请在断点处添加媒体查询，该断点处的视口不够大，不允许图像彼此相邻放置。我发现视口低于666px时就是这种情况，此时请删除使图像浮动并居中对齐。

@media screen and (max-width: 666px) {
  div.gallery {
    float: none;
    margin-left: auto;
    margin-right: auto;
  }
}

请参见下面的演示

@media only screen and (max-width: 600px) {
  .boxGallery {
    margin-left: 50%;
    margin-right: 50%;
  }
}

.GalleryBox {
  display: block;
  padding-left: 100px;
  padding-right: 100px;
  width: 100%;
}

.boxGallery {
  display: block;
  margin-left: auto;
  margin-right: auto;
  width: 80%;
}

.boxGallery::after {
  content: "";
  display: table;
  clear: both;
}

div.gallery {
  margin: 5px;
  float: left;
  width: 250px;
}

div.gallery img {
  width: 250px;
  height: 190px;
}

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

@media screen and (max-width: 666px) {
  div.gallery {
    float: none;
    margin-left: auto;
    margin-right: auto;
  }
}
