[英]How do I align Box shadow to the Center of the screen?
請問什么是使盒子陰影出現在屏幕中央的最佳方法? 通過尋找,我沒有找到任何可以在那個光中提供某種形式的幫助的東西。 我寫的 css 如下所示:
.paypalPayment{
width: 700px;
height: 52px;
margin:59px;
position:absolute;
border:2px solid #fff;
background: url(pp2.png) no-repeat;
box-shadow: 10px 10px 5px #ccc;
-moz-box-shadow: 10px 10px 5px #ccc;
-webkit-box-shadow: 10px 10px 5px #ccc;
-khtml-box-shadow: 10px 10px 5px #ccc;
}
這已經被放在了應該在 HTML 區域中顯示 Boxshadow 的 div 中。 我只是想讓它居中。 我該如何處理這樣的事情?

Box-Shadow 不是來到屏幕的中心,而是轉到頁面的左開始。 現在這是 css class 應該對齊 css,我嘗試使用align-items: center;
原來它從來沒有成功。
我的 Html 代碼如下所示:
import React from 'react';
import './app-styles.css';
import Vector from './Vector.png'
import ie_logo from './ie_logo.png';
import {Link} from 'react-router-dom';
function HomePage() {
return (
<div className="App">
<header className="header">
<img src={Vector} style={{margin:7, flexDirection:'column', alignItems: 'center'}} alt="Vector" />
<img src={ie_logo} style={{margin:7, flexDirection: 'row', width:114, height:25}} alt="ie_logo" />
<p className="needhelpText">NEED HELP?</p>
</header>
<form>
<div className="InstructionText">
payment
</div>
<div className="paypalPayment" >
</div>
</form>
<footer className="footer">
<a href="#" className="footerLinks"> Privacy Policy | </a>
<a href="#" className="footerLinks">Do Not Sell My Personal Information | </a>
<a href="#" className="footerLinks">Advertising Guidelines | </a>
<a href="#" className="footerLinks">Site Map </a>
<div className="copyrightText">

</div>
<div className="footerLogo">
<img src={ie_logo} alt="ie_logo" />
</div>
</footer>
</div>
);
}
export default HomePage;
這是我的 CSS
.header{
background-color: #007FC0;
width: 100%;
padding: 25px 0;
}
.container{
flex : 1 1 auto;
color:white;
}
.needhelpText{
text-align: right;
font-weight: bold;
color: white;
margin-left: 22px;
display: inline-block;
padding: 10px;
float: right;
font-family:'Gill Sans', 'Gill Sans MT', Calibri, 'Trebuchet MS', sans-serif;
font-size: medium;
}
.copyrightText{
color: white;
font-size: 14px;
font-family: 'Gill Sans', 'Gill Sans MT', Calibri, 'Trebuchet MS', sans-serif;
}
.footerLinks{
color: white;
display: inline-block;
font-size: 14px;
text-decoration: none;
font-family:'Gill Sans', 'Gill Sans MT', Calibri, 'Trebuchet MS', sans-serif;
}
.footerLogo{
float: right;
display:flex;
margin-right: 17px;
margin-left: 22px;
text-align: center;
width: 114px;
height : 30px;
}
.footer{
position: fixed;
left: 0;
padding: 10px;
bottom: 0;
width: 100%;
height: 70px;
background-color: #16192C;
}
.InstructionText {
margin-bottom: auto;
font-family: Arial, Helvetica, sans-serif;
font-size: 35px;
justify-content: center;
color: #007FC0;
text-transform: uppercase;
font-style: italic;
font-weight:bolder;
display: flex;
}
.InstructionText:after {
content: "";
border-bottom: 4px solid #FF9900;
width: 100px;
margin-bottom: 7px;
width: 549px;
}
.paypalPayment{
width: 700px;
height: 52px;
margin:59px;
align-items: center;
position:absolute;
border:2px solid #fff;
background: url(pp2.png) no-repeat;
box-shadow: 10px 10px 5px #ccc;
-moz-box-shadow: 10px 10px 5px #ccc;
-webkit-box-shadow: 10px 10px 5px #ccc;
-khtml-box-shadow: 10px 10px 5px #ccc;
}
負責執行此操作的 CSS 與 class paypalPayment
那么請我如何將 boxshadow 推到中心?

到目前為止,我想我已經把它放在了中心。 現在它相互碰撞。 現在看起來像這樣
我怎么反過來空間呢? 我對 CSS 有點陌生
我想這是你想做的
