我知道可以specify an element's height relative to its width,因为百分比边距和填充值是相对于宽度计算的。是否可以做相反的 - 相对于高度的宽度?
答案 0 :(得分:9)
我找到了一种没有Javascript的方法。使用比率制作图像,并将其嵌入HTML中,相应地缩放,以便父元素可以inline-block
适合图像大小。
<!-- height of the outer container -->
<div style="height: 200px">
<!-- this will resize to 200px and maintain its aspect ratio --->
<div style="display: inline-block; position: relative;">
<img src="aspectratio.png" style="height: 100%; width: auto;" />
<div style="position: absolute; top: 0; left: 0; right: 0; bottom: 0">
<!-- Everything in here can party on the fact that their parent
has the correct aspect ratio -->
</div>
</div>
</div>
