只有当我设置精确的高度时,浏览器才会显示div。但是我想根据内容创建可调整大小的div。尝试高度:自动和高度:100%。没有帮助
我的div看起来像这样。它是侧栏和内容的背景div。
.wrapper { width: 80%; height:200px; max-width: 1260px; min-width: 780px; margin: 0 auto; background-image:url(core/design/img/transfff.png); -moz-border-radius: 15px 15px 0px 0px; border-radius: 15px 15px 0px 0px; }
UPDATE
我的html看起来像这样
<!DOCTYPE HTML> <html> <head> <Meta charset="utf-8"> <title>Untitled Document</title> <style type="text/css"> body { font: 100%/1.4 Verdana,Arial,Helvetica,sans-serif; background-image: url(core/design/img/bg.png); background-position:top left; background-size:100%; background-color:#fff; background-repeat:no-repeat; margin: 0; padding: 0; color: #000; } ul,ol,dl { padding: 0; margin: 0; } h1,h2,h3,h4,h5,h6,p { margin-top: 0; padding-right: 15px; padding-left: 15px; a img { border: none; } a:link { color:#414958; text-decoration: underline; } a:visited { color: #4E5869; text-decoration: underline; } a:hover,a:active,a:focus { text-decoration: none; } .container { width: 80%; max-width: 1260px; min-width: 780px; margin: 0 auto; } .wrapper { width: 80%; height:200px; max-width: 1260px; min-width: 780px; margin: 0 auto; background-image:url(core/design/img/transfff.png); -moz-border-radius: 15px 15px 0px 0px; border-radius: 15px 15px 0px 0px; overflow: visible } .header { padding:20px; } .sidebar1 { float: left; width: 20%; padding-bottom: 10px; } .content { padding: 10px 0; width: 60%; float: left; } .sidebar2 { float: left; width: 20%; padding: 10px 0; } .content ul,.content ol { padding: 0 15px 15px 40px; } ul.nav { list-style: none; border-top: 1px solid #666; margin-bottom: 15px; } ul.nav li { border-bottom: 1px solid #666; } ul.nav a,ul.nav a:visited{ padding: 5px 5px 5px 15px; display: block; text-decoration: none; color: #000; } ul.nav a:hover,ul.nav a:active,ul.nav a:focus { background: #6F7D94; color: #FFF; } /* ~~The footer ~~ */ .footer { padding: 10px 0; position: relative; clear: both; } .fltrt { float: right; margin-left: 8px; } .fltlft { float: left; margin-right: 8px; } .clearfloat { / clear:both; height:0; font-size: 1px; line-height: 0px; } --> </style><!--[if lte IE 7]> <style> .content { margin-right: -1px; } /* this 1px negative margin can be placed on any of the columns in this layout with the same corrective effect. */ ul.nav a { zoom: 1; } /* the zoom property gives IE the hasLayout trigger it needs to correct extra whiltespace between the links */ </style> <![endif]--></head> <body> <div class="container"> <div class="header"><a href="#"><img src="core/design/img/logo.png" alt="Insert logo Here" name="Insert_logo" width="438px" height="95" id="Insert_logo" style=" display:block; margin:0 auto;" /></a> <!-- end .header --></div> <div class="wrapper"> <div class="sidebar1"> </div> <div class="content"> </div> <div class="sidebar2"> </div> </div> <div class="footer"> </div> </div> </body> </html>
