html – 使元素的宽度与动态大小的图像相同?

前端之家收集整理的这篇文章主要介绍了html – 使元素的宽度与动态大小的图像相同?前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我有一个灵敏的幻灯片式布局,每个图像下方都有字幕。

我试图获得与图像宽度相同的标题。问题是图像被缩放以适应垂直浏览器,我的标题是在缩放之前获取图像的宽度。

Fiddle

#big_container {
  display:block;
	position:relative;
	width:100%;
	padding-bottom:40%;
	white-space:nowrap;
	overflow-x:scroll;
	overflow-y:hidden;
}
    
#big_container>div {
	position:absolute;
	top:0;
	right:0;
	bottom:0;
	left:0;
}

.little_container {
	display:inline-block;
	height:100%;
	width:100%;
	text-align:center;
}

#big_container figure {
  display:inline-block;
	height:100%;
	margin:0;
}

figure img {
	max-height:calc(100% - 40px); /* subtract height of caption */
}

figcaption {
	display:block;
	width:100%;
	text-align:left;
	Box-sizing:border-Box;
	margin:0;
	padding:10px;
	line-height:20px;
	background-color:#ddd;
}
<div id="big_container">
  <div>

  <div class="little_container">
      <figure>
        <img src="http://placekitten.com/500/440">
        <figcaption>
          have a kitty!!1
        </figcaption>
      </figure>
  </div>
  
  <div class="little_container">
      <figure>
        <img src="http://placekitten.com/450/400">
        <figcaption>
          moar kitty!
        </figcaption>
      </figure>

  <div class="little_container">

如何根据流体图像的宽度进行缩放?
我希望得到一个纯粹的css解决方案。

更新
原来我以上的尝试partially works in chrome and opera,but exhibits some odd behavior
我没有发现关于这个问题的任何错误报告,但我不禁想知道这是否可能被认为是浏览器中的错误

为了清楚起见,以下简要概述我的具体要求:

>标题元素的宽度必须与图像的宽度相同(可以将标题文字左右对齐到图像的边缘)
>图像不得裁剪或拉伸
>图像和标题必须都适合其容器(可能是流体),使用尽可能多的空间。
>以上规则应适用于任何维度的图像
>仅CSS(与旧浏览器的兼容性不是主要问题,但它是一个加号)

可以更改html标记

解决方法

更新

根据您为此问题设置的确切要求,它不能仅用CSS解决

这是我能够想出来的最好的。

Fiddle demo 1(固定高度为文字,图像完全可见)
Fiddle demo 2(半透明可缩放文字顶部的动画图像)

我主要使用的技巧是拥有一个隐藏的img来弥补空间,然后是一个背景图像,以保持比例缩放到最大宽度/高度。

为了方便,我添加了内联样式的背景图像,因此可以在HTML内部处理内容

为了使其完美,需要一个脚本,计算标题内容并调整图像/标题的缩小/高度。
