Question

我从DynamicDrive获得了侧边栏菜单。我稍微改了一下，因此可以从右到左使用。它适用于除IE7以外的所有浏览器。经过大量的调试后，我发现当我删除<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3c.org/TR/1999/REC-html401-19991224/loose.dtd">标签时，它一切正常，但它与doctype标签无法正常工作。会发生什么是子菜单跳到屏幕左侧，它们应该是LTR（英文）版本。

以下是代码：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3c.org/TR/1999/REC-html401-19991224/loose.dtd">
<html dir="rtl">
<head>
<style type="text/css">

.sidebarmenu ul{
margin: 0;
padding: 0;
list-style-type: none;
font: bold 13px Verdana;
width: 180px; /* Main Menu Item widths */
border-bottom: 1px solid #ccc;
}

.sidebarmenu ul li{
list-style-type: none;
position: relative;
}

/* Top level menu links style */
.sidebarmenu ul li a{
display: block;
overflow: hidden; /*force hasLayout in IE7 */
color: #282828;
text-decoration: none;
padding: 6px;
border-top: 1px solid #ccc;
border-bottom: 1px solid #ccc;

}

.sidebarmenu ul li a:link, .sidebarmenu ul li a:visited, .sidebarmenu ul li a:active{
background-color: #EAE8E8;/*#012D58; /*background of tabs (default state)*/
}

.sidebarmenu ul li a:visited{
color: #282828;
}

.sidebarmenu ul li a:hover{
background-color: white;
}

/*Sub level menu items */
.sidebarmenu ul li ul{
position: absolute;
right:170px; /*Only for farsi*/
width: 170px; /*Sub Menu Items width */
top: 0;
visibility: hidden;
}

.sidebarmenu ul li ul li{
    z-index:10;
}

.sidebarmenu a.subfolderstyle{
/*background: url(/html/portlet/ext/sitemap_1/right.gif) no-repeat 97% 50%;*/
}


/* Holly Hack for IE \*/

* html .sidebarmenu ul li a { height: 1%; }
/* End */
