为什么我的“部分”不能正确居中？
我认为应该这样做：
section{
width: 80%;
margin-left: auto;
margin-right: auto;
}
这次出了什么问题？
HTML：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>LifeSymb.com</title>
<link rel="stylesheet" type="text/css" href="css/style.css" />
</head>
<body>
<section>
<article id="intro" class="scrollBlock">

CSS：
body{
font: 18px/30px Sans-serif;
color: black;
background:url('../images/bodyBG.png');
}
section{
width: 80%;
margin-left: auto;
margin-right: auto;
}
.scrollBlock{
width: 70%;
}
#intro{
background: lightgreen url(../images/dragon.jpg) left no-repeat;
/*background-size: cover;*/
}
#intro h1{
width: 677px; height: 122px;
background: url(../images/btn_intro.png);
text-indent: -9999px;
position: relative;
top: 145px;
left: 0;
}
#intro p{
position: relative;
top: 200px;
left: 350px;
width: 508px;
margin: 0 0 30px 0;
}
#intro p:nth-child(2){
font-weight: bold;
}
#slide2{
background: lightpink url(../images/texture_purple.png);
}
#dog{
background: black url(../images/dog.jpg)no-repeat;
background-size: cover;
padding-top: 400px;
}
#dog h2{
opacity: 0;
}
将此添加到CSS：
section article {margin: 0 auto;}
这意味着“将0垂直边距和auto水平边距应用于每个article作为其子级的边距section”。（JSFiddle）
您的articles小于的宽度section，因此您也必须将articles居中对齐。
