我的响应式 CSS 菜单有这个 CSS 代码:
nav, ul, li, a {
margin: 0; padding: 0;
}
a {
text-decoration: none;
}
.container {
width: 100%;
margin: 10px auto;
}
.toggleMenu {
display: none;
background: #666;
padding: 10px 15px;
color: #fff;
}
.nav {
list-style: none;
*zoom: 1;
background:#f36f25;
}
.nav:before,.nav:after {
content: " ";
display: table;
}
.nav:after {
clear: both;
}
.nav ul {
list-style: none;
width: 9em;
}
.nav a {
padding: 10px 15px;
color:#fff;
}
.nav li {
position: relative;
}
.nav > li {
float: left;
border-top: 1px solid #104336;
}
.nav > li > .parent {
background-image: url("images/downArrow.png");
background-repeat: no-repeat;
background-position: right;
}
.nav > li > a {
display: block;
}
.nav li ul {
position: absolute;
left: -9999px;
}
.nav > li.hover > ul {
left: 0;
}
.nav li li.hover ul {
left: 100%;
top: 0;
}
.nav li li a {
display: block;
background: #1d7a62;
position: relative;
z-index:100;
border-top: 1px solid #175e4c;
}
.nav li li li a {
background:#249578;
z-index:200;
border-top: 1px solid #1d7a62;
}
@media screen and (max-width: 768px) {
.active {
display: block;
}
.nav > li {
float: none;
}
.nav > li > .parent {
background-position: 95% 50%;
}
.nav li li .parent {
background-image: url("images/downArrow.png");
background-repeat: no-repeat;
background-position: 95% 50%;
}
.nav ul {
display: block;
width: 100%;
}
.nav > li.hover > ul , .nav li li.hover ul {
position: static;
}
}
但我无法让菜单项在菜单/页面的中心对齐
这是完整代码的小提琴:
