文字一直在我的图片右侧

Question

我的问题

我正在尝试为每张图片制作一个带有标题的照片库。但我遇到的问题是标题一直漂浮在图像旁边。参考请看screenshot。

CSS 片段

@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>

请提供有关如何解决此问题的任何帮助。

Answer 1

因为您正在浮动.boxGallery 中的元素，所以父项会丢失其尺寸（因为它不再考虑浮动内容）。因为孩子是浮动的，所以标题被定位为浮动的“填充物”。

您可以通过所谓的 clearfix 解决此问题。如今，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，我会为此使用 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 2

您有 .gallery 浮动，因此它从正常的 HTML 流中弹出，并且父级不知道子元素的实际高度。您的 .boxGallery 需要“clear-fix”来清除浮动元素的高度：

.boxGallery:after {
    visibility: hidden;
    display: block;
    content: "";
    clear: both;
    height: 0;
}

@media only screen and (max-width: 600px) {
  .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 {

Answer 3

由于您已浮动图像，因此它们已脱离正常流程，.boxGallery 元素的行为就像它们不再存在并且仅确认 .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;
}

你可以阅读更多关于'clearfixing' here

为了使图像居中，在断点处添加一个媒体查询，其中视口不够大，无法让图像彼此相邻我发现当视口低于 666px 时就是这种情况，此时删除浮动并居中带边距的图像。

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

请看下面的演示：

@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;
  }
}
