具有对齐内容的Flex项：间隔不正确显示

Question

我有一个带子菜单的菜单栏。我希望在菜单的同一行显示右侧的“帐户”或“个人资料”链接，我想用纯CSS3 / Flex来完成。

但是我想我的css代码有问题，因为最后一个链接（“帐户”）在主菜单下进行了diplaying，因此导航元素的justify-content: space-between无效。我该怎么办？

这是我的代码：

nav {
    font-size: 20px ;
    background-color: white;
    display: flex;
    flex-direction: row;
    justify-content: space-between;
}

nav ul {
    display: flex;
    flex-direction: row;
    margin: 0;
    padding: 0 ;
    position: absolute;
    background-color: white;
    list-style-type: none;
}

nav ul li {
    padding: 0;
    margin: 0;
}

nav ul li ul {
    display: none;
    margin: 0;
    padding: 0;
    box-shadow: 3px 3px 3px 0px #DDDDDD;
    background-color: white;
}

nav ul li:hover ul{
    display: block;
}

nav a {
    color: #333;
    display: block;
    margin: 0;
    padding: 10px 20px;
    text-decoration: none;
}

nav a:hover {
    background-color: #DDD;
}

<nav>
    <ul>
        <li><a href="#">Menu1</a>
            <ul>
                <li><a href="#">Submenu</a></li>
                <li><a href="#">Another longer submenu here</a></li>
                <li><a href="#">Yet another submenu</a></li>
                <li><a href="#">Etc. etc.</a></li>
            </ul>
        </li>
        <li><a href="#">Menu2</a></li>
        <li><a href="#">Menu3</a>
            <ul>
                <li><a href="#">My submenu 1</a></li>
                <li><a href="#">My submenu 2</a></li>
                <li><a href="#">My submenu 3</a></li>
                <li><a href="#">My submenu 4</a></li>
                <li><a href="#">My submenu 5</a></li>
                <li><a href="#">My submenu 6</a></li>
                <li><a href="#">My submenu 7</a></li>
                <li><a href="#">My submenu 8</a></li>
            </ul>
        </li>
        <li><a href="#">Menu4</a>
        </li>
    </ul>
    <a href="#">Account</a>
</nav>

好的，我刚发现错误。

nav ul { position: absolute; }

不应该在这里定位，但在这里：

nav ul li ul { position: absolute; }

所以解决了片段（希望它可以帮助其他人）......

nav {
    font-size: 20px ;
    background-color: white;
    display: flex;
    flex-direction: row;
    justify-content: space-between;
}

nav ul {
    display: flex;
    flex-direction: row;
    margin: 0;
    padding: 0 ;
    background-color: white;
    list-style-type: none;
}

nav ul li {
    padding: 0;
    margin: 0;
}

nav ul li ul {
    display: none;
    margin: 0;
    padding: 0;
    box-shadow: 3px 3px 3px 0px #DDDDDD;
    background-color: white;
    position: absolute;        
}
nav ul li:hover ul{
    display: block;
}

nav a {
    color: #333;
    display: block;
    margin: 0;
    padding: 10px 20px;
    text-decoration: none;
}

nav a:hover {
    background-color: #DDD;
}

<nav>
    <ul>
        <li><a href="#">Menu1</a>
            <ul>
                <li><a href="#">Submenu</a></li>
                <li><a href="#">Another longer submenu here</a></li>
                <li><a href="#">Yet another submenu</a></li>
                <li><a href="#">Etc. etc.</a></li>
            </ul>
        </li>
        <li><a href="#">Menu2</a></li>
        <li><a href="#">Menu3</a>
            <ul>
                <li><a href="#">My submenu 1</a></li>

                <li><a href="#">My submenu 7</a></li>
                <li><a href="#">My submenu 8</a></li>
            </ul>
