[英]HTML CSS margin-left and margin-right don't want to center a div
I'm learning css and html and i have this problem, where the margin-left and margin-right in the ".logo" div class don't want to center the div. 我正在学习css和html,并且我有此问题,其中“ .logo” div类中的margin-left和margin-right不想将div居中。 Please help because i done reserch, i checked the code and everything looks good, so I have no idea whats going on.
请帮忙,因为我完成了研究,我检查了代码,一切看起来都很好,所以我不知道发生了什么。
body { background-color: #303030; color: #ffffff; } .wrapper { width:100%; } .header { width:100px; padding:40px 0; } .logo { width:450px; font-size:48px; border: 1px solid white; margin-left: auto; margin-right: auto; }
<html lang="pl"> <head> <meta charset="utf-8"/> <title>site</title> <link rel="stylesheet" href="style.css" type="text/css"/> </head> <body> <div class="wrapper"> <div class="header"> <div class="logo"> LOGO </div> </div> </div> </body> </html>
Your header is only 100px
while your logo is 450px
, you can check this fiddle for demo . 标头仅为
100px
,徽标为450px
,可以查看此小提琴进行演示 。
.wrapper {
width: 100%;
}
.header {
width: 1000px;
padding: 40px 0;
}
.logo {
width: 450px;
font-size: 48px;
border: 1px solid white;
margin-left: auto;
margin-right: auto;
}
