aspect-ratio-trick parent 的高度 100%
Height 100% of aspect-ratio-trick parent
我有一个 parent/wrapper 容器,其高度取决于宽度,因此它使用了常用于 iframe 和视频的有用 aspect-ratio trick;也就是说,设置 height: 0
、padding-top: 53.3%
为 16:9。
我现在的问题是我在需要 height: 100%
的包装内有一个 child。但它没有考虑填充,导致无高度 child 溢出。
此代码片段说明了我的问题:
let
box = document.querySelector('.aspect-ratio')
;
document.querySelector('[name="toggle"]').onclick = function(){
let
padding_trick = 'height-0'
;
if (box.classList.contains(padding_trick)) {
box.classList.remove(padding_trick);
} else {
box.classList.add(padding_trick);
}
};
* {
box-sizing: border-box;
}
.controller {
margin-bottom: 15px;
}
.wrapper {
position: relative;
width: 400px;
}
.aspect-ratio {
background-color: beige;
}
.aspect-ratio.height-0 {
height: 0;
padding-top: 53.3%;
}
.inner {
background-color: tomato;
height: 100%;
border: 1px solid #222;
}
<div class="root">
<div class="controller">
<button name="toggle">Toggle padding-trick</button>
</div>
<div class="wrapper">
<div class="aspect-ratio height-0">
<div class="inner">
<p>Bordered content height is not 1oo%.</p>
</div>
</div>
</div>
</div>
我想要的是文本出现在框内,红色 background-color 填满框的整个高度。
What I would want is that the text appears inside the box, and that the red background-color fills the entire height of the box.
这听起来像是您希望内框绝对定位在填充技巧框之上。如果是这种情况,只需添加 position
属性就可以做到这一点。
