Answer 1

只需添加

<div class="d-flex col-xl-12 col-lg-12 col-md-12 col-sm-12 col-xs-12 bg-primary justify-content-center">

因此，通过这种方式，您可以使用 justify-content-center 声明一个弹性框，并且它们应该位于正确的位置：

Answer 2

.navBar2{
display:flex;
justify-content:center;
}

Answer 3

只需从导航栏导航中删除 ml-auto：

          <ul class="navbar-nav ml-auto">
            <li class="nav-item  ">
              <a class="nav-link firstLink" href="#">WHO WE ARE <span class="sr-only">(current)</span></a>
            </li>
            <li class="nav-item ">
              <a class="nav-link " href="#">OUR SERVICES</a>
            </li>
            <li class="nav-item">
              <a class="nav-link " href="#">OUR PROJECTS</a>
            </li>
          
            <li class="nav-item">
              <a class="nav-link" href="#">CONTACT US</a>
            </li>
          
           <li class="nav-item">
              <a class="nav-link" href="#">CAREERS</a>
            </li>
          </ul>

并使其成为m-auto，这样自动边距会同时应用于左右两侧。
