我的横向菜单有问题。菜单未在IE9中显示内联。它在Firefox，Safari和Chrome中都很好用。不幸的是，我在Mac上工作，无法访问IE来测试它。你有什么想法，为什么它不能正常工作？
这是我的CSS：
.navigationwide {
background-image: url('images/site_gray_bg.png');
border-top: 3px solid #efa320;
-moz-box-shadow: 0px 10px 20px rgba(0,0,0,0.3);
-webkit-box-shadow: 0px 10px 20px rgba(0,0,0,0.3);
box-shadow: 0px 10px 20px rgba(0,0,0,0.3);
}
.navigation {
margin: auto;
width: 960px;
text-align: center;
}
.menu {
margin: 0;
padding: 0;
}
.menu ul {
list-style: none;
margin: 0;
padding: 0;
position: relative;
}
.menu li {
display: inline-block;
padding: 0;
}
.menu li a {
display: block;
font-family: 'Medula One', cursive;
font-size: 30px;
color: #ffffff;
margin: 0;
padding: 15px 25px;
text-align: center;
text-decoration: none;
text-transform: uppercase;
}
.menu li a:hover {
color: #efa320;
}
/* ----------------- SUBMENU START ----------------- */
.menu li ul {
background-image: url('images/site_gray_bg.png');
display: none;
height: auto;
padding: 0;
margin: 0;
position: absolute;
z-index: 200;
}
.menu li:hover ul {
display: block;
}
.menu li li {
background: none;
display: block;
float: none;
margin: 0;
padding: 0;
}
.menu li:hover li a {
background: none;
}
.menu li ul a {
display: block;
font-family: 'Medula One', cursive;
font-size: 24px;
color: #ffffff !important;
margin: 0;
padding: 10px 25px;
text-align: left;
text-decoration: none;
text-transform: uppercase;
border-bottom: 1px solid rgba(255,255,255,.1);
}
.menu li ul a:hover {
color: #ffffff;
background-color: #efa320;
}
