Question

我把品牌放在中心导航栏上，我希望导航到左侧并导航到右侧。所有这些工作都很好，但我有问题如何对齐左右导航中心，如下面的截图所示。

这是我的代码：

＆＃13;

.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;
}

＆＃13;

</nav>

Answer 1

您好，您可以尝试这样做以达到您想要的效果。

首先删除.mr-auto上的课程<ul class="navbar-nav">，然后添加

.custom-css到<div class="collapse navbar-collapse custom-css" id="navbarSupportedContent">，因为.navbar-collapse已经设置为display:flex，我们现在只需将justify-content: space-around;设置为.custom-css

请参阅以下代码。

.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;
}

            </li>
        </ul>
    </div>
</nav>

希望这有帮助

Answer 2

你有2个ul类，在一个类中组合所有

元素，然后使用Div类Container，然后使用justify content = center将所有元素放在中心。请参阅下面的代码。

.container {
    display: flex;
    align-content: center;
    justify-content: center;
    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;
}

在徽标的左侧和右侧制作2个可折叠导航会更好（并且反应灵敏）......

<nav class="navbar navbar-expand-lg navbar-dark bg-dark position-relative">
        <div class="navbar-collapse collapse w-100 dual-collapse2 order-1 order-md-0">
            <ul class="navbar-nav ml-auto">
                <li class="nav-item active">
                    <a class="nav-link" href="#">Почетна</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">О нама</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Мени</a>
                </li>
            </ul>
        </div>
        <div class="mx-auto order-0 mt-lg-5 mt-0 order-md-1 position-relative">
            <a class="mx-auto" href="#">
                <img src="//placehold.it/250" class="rounded-circle">
            </a>
            <button class="navbar-toggler" type="button" data-toggle="collapse" data-target=".dual-collapse2">
                <span class="navbar-toggler-icon"></span>
            </button>
        </div>
        <div class="navbar-collapse collapse w-100 dual-collapse2 order-2 order-md-2">
            <ul class="navbar-nav mr-auto">
                <li class="nav-item">
                    <a class="nav-link" href="#">Прославе</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Галерија</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Локација</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Контакт</a>
                </li>
            </ul>
        </div>

然后你只需要一点CSS导航高度：

@media (min-width: 992px) {
    .navbar {
        height:150px;
    }
}
