我正在尝试复制他们在apple.com网站上用于主导航的Apple导航菜单栏，这里只使用HTML，CSS和一张图片，我遇到了一些问题。
我似乎无法弄清楚为什么我的导航菜单栏没有出现！
链接在这里： http://www.marioplanet.com
如果您不想在线观看网站，我也会在这里提供代码。
这是我的HTML：

这是我的default.css：
body {
background-color: #666666;
font-family:Verdana, Arial, Helvetica, sans-serif;
}
#header {
background-color: #DDDDDD;
width: 1130px;

}
#content {

任何帮助都会很棒！

答案 0 :(得分：1)
您可以通过调整#globalheader #globalnav li a声明来解决此问题：
#globalheader #globalnav li a {
float: left;
width: 103px;
/* Give the links height and knock their text out of view */
height: 38px;
text-indent: -1000em;
overflow: hidden;
background-image:url(/images/globalnav/wanzart.png);
_background-image: url(/images/globalnav/wanzart.png);
background-repeat: no-repeat;
}
它现在不适合您的原因是因为您将链接设置为0高度和隐藏溢出。这样做有效地使元素消失。
通过为链接指定高度，您可以显示背景图像，并且文本缩进可确保浏览器呈现的文本不会妨碍。
