css - 如何在 anchor 标签内居中放置多个图像

Question

我希望图像居中，但无法在中、大 和超大 屏幕上执行此操作

 <nav class="navbar">
    <div class="row">
        <div class="col-12 d-flex justify-content-center">
            <a href="/html"><img src="./images/devices.png" alt="devices"></a>
            <a href="/html"><img src="./images/media.png" alt="media"></a>
            <a href="/html"><img src="./images/logo.png" alt="logo"></a>
            <a href="/html"><img src="./images/stream.png" alt="stream"></a>
            <a href="/html"><img src="./images/logout.png" alt="logout"></a>
        </div>
    </div>
</nav>

我尝试了 stackoverflow 网站上提供的不同解决方案，但都没有奏效。请帮忙，我是新手

Answer 1

我不太明白你需要什么，但我想你可以引用以下2页:

• > .nav class
• > .navbar class

通常导航是带有多个链接或下拉菜单的栏。所以我看不出这有什么道理。

下面是 2 个示例，其中一个是我水平排列的 .nav 类。一个是我垂直排列的 .navbar 类。

元素的内容居中。

希望这对您有所帮助。

.navbar, .nav {
background-color: #A4A4A4;
border: 1px solid red;
}

/* for the purpose of demonstration, I added borders to the Nav-ul */
#top-menu {
border: 1px solid red;
}

.nav-link {
width: 100px;
text-align: center;
/* for the purpose of demonstration, I added borders to the list items */
border: 1px solid black;
}

.dont_copy_this {height: 50px;}
