如何将 a 标签的文本移动到导航栏的中间

Question

我在将 a 标签的文本移动到 nav 栏的中间时遇到问题，如果我使用 padding-top 标签溢出的悬停，所以我隐藏了它在 nav 栏上使用 overflow: hidden;，这个问题的最佳解决方案是什么？。请注意，我的问题不是关于如何将作为其他元素的子元素的元素居中，例如 div 中的 p 标记，而且我要求在当前情况下采用最佳方法，我猜很多初学者觉得这很棘手。

html, body {
    margin: 0px;
}
header {
    display: grid;
    grid-template-columns: 1fr 1fr;
    color: white;
    background: black;
}

header .title{
    padding-left: 10px;
    font-size: 2rem;
}
header h1 {
    margin: 0;
}

nav {
    overflow: hidden;
}

nav ul {
    display: grid;
    grid-template-columns: 1fr 1fr 1fr;
    margin: 0;
    height: 100%;
}

nav ul li {
    list-style-type: none;
    text-align: center;
}

nav a {
    color: white;
    font-weight: bold;
    text-decoration: none;
    font-size: 1.4rem;
    display: block;
    height: 100%;
    padding-top: 20px;
}
nav a:hover {
    background-color: red;
}

Answer 1

nav a {
  display: flex;
  align-items: center;
}

...将它们垂直居中，只要顶部和底部填充值相等：

html, body {
    margin: 0px;
}
header {
    display: grid;
    grid-template-columns: 1fr 1fr;
    color: white;
    background: black;
}

header .title{
    padding-left: 10px;
    font-size: 2rem;
}
header h1 {
    margin: 0;
}

nav {
    overflow: hidden;
}

nav ul {
    display: grid;
    grid-template-columns: 1fr 1fr 1fr;
    margin: 0;
    height: 100%;
}

nav ul li {
    list-style-type: none;
    text-align: center;
}

nav a {
    color: white;
    font-weight: bold;
    text-decoration: none;
    font-size: 1.4rem;
    height: 100%;
    display: flex;
    align-items: center;
    justify-content: center;
    padding: 0;
}
nav a:hover {
    background-color: red;
}

            <div class="title">
                <h1>Biblio</h1>
            </div>
            <nav>
                <ul>
                    <li><a href="#">home</a></li>
                    <li><a href="#">languages</a></li>
                    <li><a href="#">books</a></li>
                </ul>
            </nav>
        </header>
    </div>

但是，更大的问题是您使用网格使所有按钮的宽度相等。普遍接受的顶部导航菜单范例是：每个元素占用所需的宽度量 + 一些填充。如：

nav ul {
  display: flex;
  justify-content: flex-end;
}

nav a {
  display: flex;
  align-items: center;
  padding: 0 .75em;
}

html, body {
    margin: 0px;
}
header {
    display: grid;
    grid-template-columns: 1fr 1fr;
    color: white;
    background: black;
}

header .title{
    padding-left: 10px;
    font-size: 2rem;
}
header h1 {
    margin: 0;
}

nav {
    overflow: hidden;
}

nav ul {
    display: flex;
    justify-content: flex-end;
    margin: 0;
    height: 100%;
}

nav ul li {
    list-style-type: none;
    text-align: center;
}

nav a {
    color: white;
    font-weight: bold;
    text-decoration: none;
    font-size: 1.4rem;
    height: 100%;
    display: flex;
    align-items: center;
    padding: 0 .75em;
}
nav a:hover {
    background-color: red;
}
