NavBar的中心内容 - BootStrap

Question

我试图将导航栏的内容集中在一起但是，我无法使其正常工作

我认为一切似乎都比中心更左对齐，但我没有使用浮动：离开任何地方

我正在尝试将图像和导航居中

码：

            <div class="container">
                <a class="navbar-brand"><img src="Final.png"/></a>

                <div class="navbar-header">
                    <button class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
                        <span class="icon-bar"></span>
                        <span class="icon-bar"></span>

                <div class="navbar-collapse collapse">
                    <ul class="nav navbar-nav">
                        <li><a href="#">Home</a></li>
                        <li><a href="#">Services</a></li>
                        <li><a href="#">About Us</a></li>
                        <li><a href="#">Contact Us</a></li>
                    </ul>

        <footer class="footer">

                <h6 class="text-center">Copyright &copy; Soni Computer Repairs</h6>
                <p class="text-center">www.SoniRepairs.com</p>
            </div>
        </footer>
    </body>
</html>

CSS：这是CSS代码

.nav, .navbar-nav {
    text-align: center;
}

.container img {
    height:100%;
    display: block;
    margin-right: auto;
    margin-left: auto;
}

.footer {
  position: absolute;
  bottom: 0;
  width: 100%;
  height: 60px;
  background-color: #f5f5f5;
}

@media screen and (max-width: 500px) {

    .navbar-nav, .container img{
        margin-left: auto;
        margin-right: auto;
        display: table;
        table-layout: fixed;
        float:none;
    }

    .navbar-brand {
        position: absolute;
        width: 100%;
        left: 0;
        text-align: center;
        margin: auto;
    }
}

Answer 1

HTML：我在ul中移动了navbar-brand

<div class="navbar-collapse collapse" aria-expanded="false" style="height: 1px;">
    <ul class="nav navbar-nav">
        <a class="navbar-brand"><img src="Final.png"></a><li><a href="#">Home</a></li>
        <li><a href="#">Services</a></li>
        <li><a href="#">About Us</a></li>
        <li><a href="#">Contact Us</a></li>
    </ul>
</div>

CSS：我添加了这3行

@media (min-width: 768px) {
    .navbar-nav { float: none; }
    .navbar-nav>li { float: none; display: inline-block; }
    .navbar>.container .navbar-brand, .navbar>.container-fluid .navbar-brand { float: none; display: inline-block; }
}

它正在以这种方式为我工作。 享受=）
