Question

我为一个工作做了一个登陆页面并且做了导航栏然后我想通了我必须将导航栏固定到顶部，在我修复它后，第二个栏的崩溃只是在我甚至没有悬停时出现在上面。不得不为下一个项目添加更多的保证金，以“有点”工作，但有点难看

.fixed-top {
    position: fixed;
    right: 0;
    left: 0;
    z-index: 1030;
    top: 0;
    border-width: 0 0 1px;
}

#nav ul li a {
    display: block;
    padding: 7px 15px;
    text-decoration: none;
    font-weight: bold;
    color: #FFFFFF;
}

#nav li a:hover {
    color: #000000;
    background-color: #fff; 
}

#nav .navbar-izquierda ul {
    width: 100%;
    float: left;
    margin: auto;
    padding: 0;
    list-style: none;
