如何在添加内容时自动调整div高度？

Question

我正在创建一个移动应用程序，用户将内容发布到Feed。对于每个帖子都有一个单独的div区域，他可以添加内容和图片。问题是，当我在同一个div中粘贴一个虚拟文本和一张照片时，高度已关闭并且不会自行调整。

下面的石化公司全面覆盖，当我将它设置为一个特定的高度

这里的灰色背景区是什么样子，现在，当我将高度设置为自动。注意灰色背景区域被缩短。

的目标是在div区域自动调整到高度，无论用户添加的内容。我试过height:auto,height:auto !important,height: 100%,height:100 !important和overflow:hidden。这些都没有给我我想要的结果。使灰色背景区域自动覆盖所有内容的最佳方法是什么？我会接受使用JavaScript或jQuery来做到这一点的答案。

只要你没有在样式表中的一切position:absolute将水到渠成，请确保您的位置设定为relative和auto离开高度（这应该是默认值）

#small_div { 
 
    padding: 2rem; 
 
    background: orange; 
 
} 
 
#large_div { 
 
    padding: 2rem; 
 
    background: lime; 
 
}

<div id="small_div"> 
 
    123 
 
</div> 
 
<div id="large_div"> 
 
1 In the beginning God created* the heaven and the earth. 2 And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. 3 And God said, Let there be light: and there was light. 4 And God saw* the light, that it was good: and God divided* the light from the darkness. 5 And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day. 6 And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters. 7 And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so. 8 And God called the firmament Heaven. And the evening and the morning were the second day. 9 And God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so. 10 And God called the dry land Earth; and the gathering together of the waters called he Seas: and God saw that it was good. 11 And God said, Let the earth bring forth grass, the herb yielding seed, and the fruit tree yielding fruit after his kind, whose seed is in itself, upon the earth: and it was so. 12 And the earth brought forth grass, and herb yielding seed after his kind, and the tree yielding fruit, whose seed was in itself, after his kind: and God saw that it was good. 13 And the evening and the morning were the third day. 14 And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years: 15 And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so. 16 And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also. 17 And God set them in the firmament of the heaven to give light upon the earth, 18 And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good. 19 And the evening and the morning were the fourth day. 20 And God said, Let the waters bring forth abundantly the moving creature that hath life, and fowl that may fly above the earth in the open firmament of heaven. 21 And God created great whales, and every living creature that moveth, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind: and God saw that it was good. 22 And God blessed them, saying, Be fruitful, and multiply, and fill the waters in the seas, and let fowl multiply in the earth. 23 And the evening and the morning were the fifth day. 24 And God said, Let the earth bring forth the living creature after his kind,
