我有一个水平和垂直居中的模式,主体内容在其大时滚动。
但是,当身体内容小于模态高度时,模态不会调整为其内容大小。
我尝试仅使用max-height而不是height,但是我的模态代码中断了...
注意:整页运行代码以查看正文内容下方的空白
.cover {
background-color: rgba(0, 0, 0, 0.4);
bottom: 0;
height: 100%;
left: 0;
padding: 0;
position: fixed;
right: 0;
top: 0;
width: 100%;
z-index: 200;
}
.modal {
background-color: white;
margin: 10% auto;
max-width: 400px;
height: 60vh;
max-height: 60vh;
position: relative !important;
}
.scrollView {
position: relative;
border: 2px solid red;
height: calc(60vh - 100px);
margin: 50px 0;
top: 50px;
overflow: scroll;
z-index: 800;
}
div.header {
display: flex;
align-items: center;
height: 50px;
max-height: 50px;
top: 0;
position: absolute;
background: lightgreen;
width: 100%;
z-index: 900;
justify-content: space-between;
}
.header div {
padding: 0 20px;
}
div.footer {
display: flex;
justify-content: center;
align-items: center;
position: absolute;
bottom: 0;
height: 50px;
background: orange;
width: 100%;
}
.body {
overflow-y: scroll;
}

我该如何解决?

您可以像下面那样简化代码,并依赖于模式内部的flexbox而不是position:absolute;
.cover {
background-color: rgba(0, 0, 0, 0.4);
bottom: 0;
left: 0;
position: fixed;
right: 0;
top: 0;
z-index: 200;
display:flex;
align-items:center;
justify-content:center;
}
.modal {
background-color: white;
max-width: 400px;
width:100%;
max-height: 60vh;
display:flex;
flex-direction:column;
}
.scrollView {
flex-grow:1;
border: 2px solid red;
overflow: auto;
}
div.header,
div.footer{
display: flex;
align-items: center;
justify-content: space-between;
height: 50px;
background: lightgreen;
padding: 0 20px;
flex-shrink:0;
}
div.footer {
background: orange;
justify-content: center;
}
