html - Bootstrap 在中心对齐导航栏

Question

我将品牌放在中央导航栏上，我希望导航到左侧，导航到右侧。所有这些都很好，但我有疑问如何像下面的屏幕截图那样对齐左右导航中心。

这是我的代码:

.navbar {
    position: relative;
    height:150px;
}
.brand {
    position: fixed;
    top: 23%;
    left: 50%;
    /* bring your own prefixes */
    transform: translate(-50%, -50%);
    margin-left: -50px !important;  /* 50% of your logo width */
    display: block;
}

    <a class="brand" style="margin: 0; float: none;" href="#">
        <img src="img/profile.png" width="250" />
    </a>
    <div class="collapse navbar-collapse" id="navbarSupportedContent">

            <li class="nav-item">
                <a class="nav-link" href="#">Мени</a>
            </li>
        </ul>


        <ul class="nav navbar-nav">

            <li class="nav-item">
                <a class="nav-link" href="#">Контакт</a>
            </li>
        </ul>
    </div>
</nav>

您好，您可以尝试这样做来实现您想要的效果。

首先删除类.mr-auto在你的 <ul class="navbar-nav">然后添加

一类.custom-css至 <div class="collapse navbar-collapse custom-css" id="navbarSupportedContent">自 .navbar-collapse已设置为 display:flex , 我们现在只需设置 justify-content: space-around;到 .custom-css

请看下面的代码。

.navbar {
    position: relative;
    height:150px;
}
.brand {
    position: fixed;
    top: 23%;
    left: 50%;
    /* bring your own prefixes */
    transform: translate(-50%, -50%);
    margin-left: -50px !important;  /* 50% of your logo width */
    display: block;
}

.custom-css{
  justify-content: space-around;
}
