问题描述
我正在尝试创建一个响应式div,但是由于某些原因,将高度更改为百分比只会忽略高度.我只能添加一个固定高度.
I am trying to make a responsive div, but for some reason, changing the height to percent just ignores the height. I can only add a fix height.
在下面的示例中我要更改的div是mainContainer
The div I want to change in the example below is the mainContainer
html, body{
width:100%;
height: 100%;
}
.mainContainer{
width:150%;
height:550px; /*I want this to be 60% or something*/
padding:10px;
background-color:#080808;
border-radius:5px;
}
.textContainer{
width:55%;
height:100%;
float: left;
background-color:#666666;
border-radius:10px 0 0 10px; /*TL TR BR BL*/
}
#map1 {
width: 45%;
height: 100%;
margin-top:-15px;
float:right;
display:inline;
border-radius:0 15px 15px 0; /*TL TR BR BL*/
}
.contentBox{
width:96%;
height:100%;
color:#F2F2F2;
font-size:100%;
padding-right:3%;
padding-left:3%;
font-family: Arial, "Helvetica Neue", Helvetica, sans-serif;
}
<section class="mainContainer">
<div class="textContainer">
<div class="intro">
<div class="contentBox">
</div>
</div>
</div>
<div id="map1"></div>
</section>
推荐答案
您要为其赋予高度的元素的父div必须具有设置的高度,以便您为子元素赋予高度%
Your parent div to the element you are trying to give a height to needs to have as set height in order for the you to give the child element a height %.
.wrapper { width: 200px; height: 200px; background-color: black; }
.content { width: 100%; height: 60%; background-color: red; }
<div class="wrapper">
<div class="content"></div>
</div>
在您的示例中,只需确保将.mainContainer
的父级设置为高度,然后可以将高度设置为60%
In your example just make sure the parent of .mainContainer
has a height set to it and then you can make the height 60%
