通过使用 d-none bootstrap 使元素消失来防止换行

Question

我正在构建一个包含顶部栏菜单的响应式网站。这个菜单有很多选项，非常适合大屏幕显示。不幸的是，对于手机等较小的视口，所有这些选项都不适合，按钮最终会环绕。

普通视口：

手机：

这是代码片段：

<header class="header" id="header">

        <div class="header_toggle" id="toggle-up"> <i class="fas fa-bars secondary-bs-color" id="header-toggle"></i></div>

        <div id="nav-buttons" class="me-5 d-sm-flex">

            <div class="container me-2">
                <div class="row">
                    <span class="text-white text-end">Level 1</span>
                </div>
                <div class="progress" style="width: 100px; height: 5px;">
                    <div class="progress-bar bg-secondary" style="width: 70%;" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100"></div>
                </div>
            </div>
            
            

            <button class="btn btn-primary-outline me-2"><i class="far fa-envelope fa-lg text-field-grey"></i></button>

            <button class="btn btn-primary-outline me-2"><i class="fas fa-user fa-lg text-field-grey"></i></button>

            <div class="dropdown me-2">
                <button class="border border-field-grey btn btn-primary dropdown-toggle" type="button" id="dropdownMenuButton1" data-bs-toggle="dropdown" aria-expanded="false">
                  <span class="text-field-grey">TC</span>
                  <span>0.00</span>
                </button>
                <ul class="dropdown-menu bg-field-grey-transparency" aria-labelledby="dropdownMenuCoins">
                  <li><a class="coin-dropdown-item dropdown-item" href="#">Action</a></li>
                  <li><a class="coin-dropdown-item dropdown-item" href="#">Another action</a></li>
                  <li><a class="coin-dropdown-item dropdown-item" href="#">Something else here</a></li>
                </ul>
            </div>

            <a type="button" class="white-bs-color fw-bold btn btn-secondary">Deposit</a>
        </div>
</header>

为了避免这个问题，我决定使用 bootstrp5 组合 d-none d-flex-sm 类 (https://getbootstrap.com/docs/5.0/utilities/display/)

<div id="nav-buttons" class="me-5 d-sm-flex">

            <div class="container me-2 d-none d-sm-block">
                <div class="row">
                    <span class="text-white text-end">Level 1</span>
                </div>
                <div class="progress" style="width: 100px; height: 5px;">
                    <div class="progress-bar bg-secondary" style="width: 70%;" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100"></div>
                </div>
            </div>
            
            

            <button class="btn btn-primary-outline me-2"><i class="far fa-envelope fa-lg text-field-grey"></i></button>

            <button class="btn btn-primary-outline me-2"><i class="fas fa-user fa-lg text-field-grey"></i></button>

            <div class="dropdown me-2">
                <button class="border border-field-grey btn btn-primary dropdown-toggle" type="button" id="dropdownMenuButton1" data-bs-toggle="dropdown" aria-expanded="false">
                  <span class="text-field-grey">TC</span>
                  <span>0.00</span>
                </button>
                <ul class="dropdown-menu bg-field-grey-transparency" aria-labelledby="dropdownMenuCoins">
                  <li><a class="coin-dropdown-item dropdown-item" href="#">Action</a></li>
                  <li><a class="coin-dropdown-item dropdown-item" href="#">Another action</a></li>
                  <li><a class="coin-dropdown-item dropdown-item" href="#">Something else here</a></li>
                </ul>
            </div>

            <a type="button" class="white-bs-color fw-bold btn btn-secondary d-none d-sm-flex">Deposit</a>
        </div>
</header>

但它们最终还是会换行，尽管小屏幕中的元素有很多 space:

有没有人知道我们如何解决这个问题？
