我想要在某些文字上方显示图像。文本可能很长或很短。在每种情况下，我希望文本粘贴在容器的底部，并且在其上方的图像在必要时缩小，以便两个项目始终适合容器高度的100％。如果需要，图像可以缩小到非常小，但我不希望它超出其自然的100％宽度或高度。
我已经使用position: absolute; bottom: 0;接近我想要的行为，但这只能确保文本从所需位置开始，并且不会调整其上方图像的大小。我怎样才能做到这一点？
#container {
height: 100vh;
width: 100vw;
position: relative;
}
div.image-content img {
/* how to force vertical resize? */
max-height: 100%;
max-width: 100%;
}
div.copy-content {
/*this fixes the text but the image does not resize */
position: absolute;
bottom: 0;
}<div id="container">

更新：在这里，我已经接近使用背景图片策略，但问题是我不希望我的图像超出其自然的100％宽度或高度，如果容器。当图像必须缩小时，background-size: contain;就是我想要的，当容器比图像大时，background-size: auto就是我想要的：
html,
body {
width: 100%;
height: 100%;
}
#container {
height: 100%;
width: 100%;
}
div.image-content {
background: url(https://placeholdit.imgix.net/~text?txtsize=33&txt=300%C3%97150&w=300&h=150);
/* desired behavior when div is LESS THAN image height */
background-size: contain;
/* desired behavior when div is GREATER THAN image height */
/*background-size: auto; */
background-position: center;
background-repeat: no-repeat;
height: 100%;
width: 100%;
}
div.copy-content {}<div id="container">

混合使用inline-block元素，绝对定位和间隔黑客，你应该能够用css实现这个目标
/* make container as big as it's content */
.container,
.copy-content,
.copy-content p {
display: inline-block;
position: relative;
}
.image {
position: absolute;
left: 0;
right: 0;
top: 0;
width: 100%;
}
.spacer {
display: block;
padding-top: 50%; /* this is specific to the image - worked out by height / width and keeps the spacer in ratio with the image */
width: 100%;
}<div class="container">
<span class="spacer"></span>

如果您愿意，可以将图像作为背景图像放在间隔符上而不是绝对定位
