这里我有一个html格式和一个css文件(style.css)。“ o-div”是外部div,“ i-div”是内部div类。
<html > <head> <title>center a div</title> <link href="../../Content/style.css" rel="stylesheet" type="text/css" /> </head> <body> <div class="o-div"> I am OUTER DIV <div class="i-div"> I am INNER DIV, I am in Center </div> </div> </body> </html>
body { background-color:Gray; padding:30px; } .o-div { padding:50px; background-color:Lime; } .i-div { background-color:Fuchsia; max-width:400px; height:200px; margin: 0 auto; text-align:center; }
