网上看到的css做的下拉菜单,为什么去掉了 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd" >就不能用呢?
HTML code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd" >
<head>
<style type="text/css">
body {font-size:1%; color:#fff;} /*get rid of the IE bug that prints the the end of the !doctype */
.menu {display:none;}
.holder {color:#000; width:90px; height:18px; display:block; background:#dca; border:1px solid #000; margin-right:1px; text-align:left; float:left; text-decoration:none; font-family:tahoma, vardana, arial, sans-serif; font-size:10px; line-height:18px; overflow:hidden;}
.holder:hover {height:auto; cursor:pointer;color:#fff; background:#000;}
a.inner, a.inner:visited {display:block; width:89px; height:18px; border-bottom:1px solid #000; text-decoration:none; color:#000; background:#eee;}
a.inner:hover {background:#add;}
p { color:#000; font-size:16px;}
</style>
<!--[if IE]>
<style type="text/css">
