小明写了段CSS代码: .overlay { position: fixed; left: 0; right: 0; top: 0; bottom: 0; background: rgba(0,0,0,.6); } 小刚看了眼,说道,你这代码可以简化,就像这样: .overlay { position: fixed; _______: 0; background: #_____; } 请补全小刚简化的对应的CSS属性和值。

可以用下面这个样式来简化:
.overlay {
position: fixed;
left: 0;
top: 0;
right: 0;
bottom: 0;
background: rgba(0,0,0,.6);
}
.overlay {
position: fixed;
_______: 0;
background: rgba(0,0,0,.6);
}
(这里的缺失部分应该是 "bottom")

import ReactModal from 'react-modal'; import './styles.css'; function MyModal() { return ( <ReactModal isOpen={true} overlayClassName="transparent-overlay" > {/* 模态框内容 */} </ReactModal> ); } .transparent-overlay { position: fixed; top: 0; left: 0; width: 100%; height: 100%; background-color: rgba(0, 0, 0, 0.5); z-index: 999; } 缩小这个模态框的大小,且周围任然不可被点击
为了缩小模态框的大小并且保持周围不可被点击,你可以在ReactModal组件中设置contentClassName属性,并在CSS中设置该类的样式,如下所示:
```
import ReactModal from 'react-modal';
import './styles.css';
function MyModal() {
return (
<ReactModal
isOpen={true}
overlayClassName="transparent-overlay"
contentClassName="custom-modal"
>
{/* 模态框内容 */}
</ReactModal>
);
}
.transparent-overlay {
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: rgba(0, 0, 0, 0.5);
z-index: 999;
}
.custom-modal {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
width: 50%;
height: 50%;
background-color: white;
z-index: 1000;
}
```
在上面的代码中,我们添加了`contentClassName="custom-modal"`属性,并在CSS中设置`.custom-modal`的样式,使得模态框在页面中垂直和水平居中,且宽度和高度都是50%。同时,我们还将模态框的z-index设置为1000,以确保它始终在遮罩层之上。
