How to center navigation on page using ul list?

Question

如何在页面上水平和垂直居中ul列表中的导航？

以下是HTML和CSS代码

.nav{
    width: 100%;
    height: 100%;
    position: fixed;
    background-color: white;
    overflow: hidden;

}

.menu a{
    padding: 30px;
    color: black;
    text-align: center;
    left: 0;
    margin:  0 auto;
    flex: none;
    display: flex;
    align-items: center;
    justify-content: center;
}

<nav class="nav">
            <ul class="menu">
                <li><a href="#">Google Store</a></li>
                <li><a href="#">Google Search</a> </li>
                <li><a href="#">Spotify</a></li>
                <li><a href="#">Spotify Blog</a></li>
                <li><a href="#">Squarespace</a></li>
                <li><a href="#">Other work</a></li>
            </ul>
        </nav>

我尝试使用CSS的flex方法来对齐项目。

You must apply flexbox properties to the container containing the item, not the item itself.

.nav {
    width: 100%;
    height: 100%;
    position: fixed;
    background-color: white;
    display: flex;
    align-items: center; 
    justify-content: center;  
}

.menu {
    list-style-type: none;
    padding: 0;
}

.menu a {
    padding: 30px;
    color: black;
    text-align: center;
    text-decoration: none;
}

<nav class="nav">
            <ul class="menu">
                <li><a href="#">Google Store</a></li>
                <li><a href="#">Google Search</a> </li>
                <li><a href="#">Spotify</a></li>
                <li><a href="#">Spotify Blog</a></li>
                <li><a href="#">Squarespace</a></li>
                <li><a href="#">Other work</a></li>
            </ul>
        </nav>

This will center your ul horizontally and vertically in the .nav container.
