如何将品牌和导航栏放在不同的行上? [英] How can I have Brand and Navbar on separate lines?

问题描述

很简单，但我对 Bootstrap 相当业余.

我了解如何使用图像作为品牌和导航项目制作导航栏.在不破解的情况下，是否有适当的方法将品牌定位在扩展导航上方?

主要是找这个；

<前>扩展-----------------------------------------|标志 |-----------------------------------------|首页 关于我们 联系方式 |-----------------------------------------倒塌-----------------|标志 ≡ |-----------------

<a class="navbar-brand" href="#"><img src="img/logo.png" alt="Logo" height="80px" width="auto"></a><ul class="navbar-nav"><li class="nav-item"><a class="nav-link" href="#">首页</a><li class="nav-item"><a class="nav-link" href="#">关于</a><li class="nav-item"><a class="nav-link" href="#">联系方式</a></nav>

解决方案

使用 flex-column 使导航栏项目堆叠成 2 行(行).

• 将徽标分组在 1 个 flexbox div 中一起切换开关 (d-flex w-100)
• 使用 mx-md-auto(自动边距)将徽标居中放置在更大的宽度上
• 使用 text-center 将 navbar-nav
中的项目居中

<div class="w-100 d-flex"><a class="navbar-brand mx-md-auto" href="#"><img src="img/logo.png" alt="Logo" height="80px" width="auto"></a><button class="navbar-toggler ml-auto" type="button" data-toggle="collapse" data-target=".navbar-collapse"><span class="navbar-toggler-icon"></span>

<div class="collapse navbar-collapse"><ul class="navbar-nav text-center"><li class="nav-item"><a class="nav-link" href="#">首页</a><li class="nav-item"><a class="nav-link" href="#">关于</a><li class="nav-item"><a class="nav-link" href="#">联系方式</a>

</nav>

Pretty simple, but I'm fairly amateur with Bootstrap.

I understand how to make the navigation bar with an image as the brand and the nav-items. Without hacking it, is there a proper way to have the brand positioned above the expanded navigation?

Basically looking for this;

EXPANDED

<nav class="mainNav navbar navbar-expand-md justify-content-center">
    <a class="navbar-brand" href="#">
        <img src="img/logo.png" alt="Logo" height="80px" width="auto">
    </a>
    <ul class="navbar-nav">
        <li class="nav-item">
            <a class="nav-link" href="#">Home</a>
        </li>
        <li class="nav-item">
            <a class="nav-link" href="#">About</a>
        </li>
        <li class="nav-item">
            <a class="nav-link" href="#">Contact</a>
        </li>
    </ul>
</nav>

解决方案

Use flex-column to make the navbar items stack in 2 rows (lines).

• group the logo & toggler together in 1 flexbox div (d-flex w-100)
• use mx-md-auto (auto-margins) to center the logo on larger widths
• use text-center to center items in the navbar-nav

<nav class="mainNav navbar navbar-expand-md navbar-light flex-column">
    <div class="w-100 d-flex">
        <a class="navbar-brand mx-md-auto" href="#">
            <img src="img/logo.png" alt="Logo" height="80px" width="auto">
        </a>
        <button class="navbar-toggler ml-auto" type="button" data-toggle="collapse" data-target=".navbar-collapse">
            <span class="navbar-toggler-icon"></span>
        </button>
    </div>
    <div class="collapse navbar-collapse">
        <ul class="navbar-nav text-center">
            <li class="nav-item">
                <a class="nav-link" href="#">Home</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">About</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Contact</a>
            </li>
        </ul>
    </div>
</nav>
