我有一个容器DIV,里面有两个DIV。第一个DIV(我的画布)需要在容器内的0 0处定位absoulte。我希望第二个DIV占据下面剩下的50%的空间。成品需要有响应。我坚持如何定位第二个DIV。
我有以下HTML:
class MorphologyCollectionViewCell: UICollectionViewCell {
var morphology : Morphology! {
didSet {
updateUI()
}
}
@IBOutlet weak var image: UIImageView!
@IBOutlet weak var title: UILabel!
private func updateUI() {
image?.image! = morphology.image
title?.text! = morphology.title
}
}
我的CSS是:
<div class="container map-container">
@include('maps.world-map')
<div id="my-canvas"></div>
<div id="their-canvas"></div>
</div>
我正在尝试找出下面画布的CSS
.map-container {
position: relative;
display: inline-block;
width: 100%;
max-width: 1728px;
max-height: 1080px;
overflow: hidden;
margin: 50px auto 0 auto;
}
#my-canvas,
#their-canvas {
padding: 0;
text-align: center;
position: absolute;
max-width: 1728px;
max-height: 540px;
width: 100%;
height: 50%;
z-index: 999998;
opacity: 0.8;
}
#my-canvas {
left: 0;
top: 0;
}
谢谢!

您可以使用botton:0px, height: 50%;
设置第二个div。查看下面的更新代码段
$('.map-container').height($(window).height()-55);
$(window).resize(function(){
$('.map-container').height($(window).height()-55);
})
&#13;
body {
padding: 0px;
margin: 0px;
}
.map-container {
position: relative;
display: inline-block;
width: 100%;
max-width: 1728px;
max-height: 1080px;
overflow: hidden;
margin: 50px auto 0 auto;
}
#my-canvas,
#their-canvas {
padding: 0;
text-align: center;
position: absolute;
max-width: 1728px;
max-height: 540px;
width: 100%;
height: 50%;
z-index: 999998;
opacity: 0.8;
}
#my-canvas {
left: 0;
top: 0;
background: red;
}
#their-canvas {
height: 50%;
bottom: 0px;
background: green;
}
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container map-container">
<div id="my-canvas">my-canvas</div>
<div id="their-canvas">their-canvas</div>
</div>

目前尚不清楚“你需要做出回应”是什么意思。
但是如果你想把你的第二个画布放在下面,你可以设置一个top: 50%;
属性。由于您使用的是画布的height
和top
的相对值,因此其父级需要定义height
或min-height

尝试以下代码,使用CSS本身就可以实现,
*{
padding:0px;
margin:0px;
}
.map-container {
position: absolute;
display: block;
width: 100%;
max-width: 1728px;
max-height: 1080px;
height:100%;
}
#my-canvas,
#their-canvas {
text-align: center;
position: absolute;
max-width: 1728px;
max-height: 540px;
width: 100%;
height: 50%;
z-index: 999998;
opacity: 0.8;
}
#my-canvas {
background: red;
}
#their-canvas {
bottom: 0px;
background: green;
}
<div class="container map-container">
<div id="my-canvas"></div>
<div id="their-canvas"></div>
</div>
