 2、Aligning items to left, right, and center within the Navbar

这是block级别的class, 用在<div>上面

The .mx-auto class can be used to align the items to the center of the navbar.
The .ms-auto class is used to align items to the right of the navbar.
The .me-auto class is used to align items to the left of that navbar.

• b4:  ml-auto => b5:ms-auto (start)
• b4:  mr-auto => b5:me-auto (end)

          <div class="mx-auto">
            <a class="navbar-brand " href="#">Navbar</a>
            <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
              <span class="navbar-toggler-icon"></span>
            </button>
        </div>

<div class="float-start">Float start on all viewport sizes</div><br>
<div class="float-end">Float end on all viewport sizes</div><br>
<div class="float-none">Don't float on all viewport sizes</div>
