如何让 div 在 bootstrap 导航栏中左对齐

Question

我是 bootstrap 的新手，我正在尝试为 zendesk 帮助门户创建导航栏。 Zendesk 使用他们自己的称为 Handlebars 的模板语言。 Handlebars 是一个简单的模板引擎，允许您在呈现时而不是设计时在页面上插入或操作内容（如果您熟悉它，它很像 Mustache）。虽然此导航栏中的所有元素都向右对齐，但我只希望搜索栏向左对齐 <div class="search-container">。是否有一个 bootstrap class 可以让我在这个搜索容器的徽标旁边“向左浮动”，同时保持其他一切完好无损并像以前一样响应？

    <nav class="navbar navbar-expand-lg navbar-light">
        <div class="logo">
            {{#link 'help_center'}}
            <img src="{{settings.logo}}" alt="{{t 'home_page' name=help_center.name}}">
            {{/link}}
        </div>

        <button type="button" class="navbar-toggler second-button" data-toggle="collapse" data-target="#navbarCollapse"
            aria-controls="navbarCollapse" aria-expanded="false" aria-label="Toggle navigation">
            <div class="animated-icon2"><span></span><span></span><span></span><span></span></div>
        </button>



        <div class="collapse navbar-collapse" id="navbarCollapse">
            <div class="navbar-nav ml-auto">

        </div>


    </nav>


</div> ```

Answer 1

您必须将 <div class="search-container"> 移到 <div class="navbar-nav ml-auto"> 之外，因为 ml-auto 会强制导航栏元素右对齐。在此处阅读有关 navbar-nav 行为的更多信息：https://getbootstrap.com/docs/4.5/components/navbar/#supported-content

对于导航栏，似乎将此元素放在<div class="collapse navbar-collapse" id="navbarCollapse">内就足够了。

您的代码之后应该如下所示：

<nav class="navbar navbar-expand-lg navbar-light">
    <div class="logo">
        {{#link 'help_center'}}
        <img src="{{settings.logo}}" alt="{{t 'home_page' name=help_center.name}}">
        {{/link}}
    </div>

    <button type="button" class="navbar-toggler second-button" data-toggle="collapse" data-target="#navbarCollapse"
        aria-controls="navbarCollapse" aria-expanded="false" aria-label="Toggle navigation">
        <div class="animated-icon2"><span></span><span></span><span></span><span></span></div>
    </button>



    <div class="collapse navbar-collapse" id="navbarCollapse">
        <div class="search-container">
            <svg xmlns="http://www.w3.org/2000/svg" width="12" height="12" focusable="false" viewBox="0 0 12 12"
                    class="search-icon">
                <circle cx="4.5" cy="4.5" r="4" fill="none" stroke="currentColor" />
                <path stroke="currentColor" stroke-linecap="round" d="M11 11L7.5 7.5" />
            </svg>
            {{search scoped=settings.scoped_kb_search submit=false}}
        </div>
        <div class="navbar-nav ml-auto">

            <a href="https://" class="nav-item nav-link">Help Portal</a>
            {{#if alternative_locales}}
            <div class="nav-item dropdown">
                <a href="#" class="nav-link dropdown-toggle" data-toggle="dropdown">{{current_locale.name}}</a>
                <div class="dropdown-menu">
                    {{#each alternative_locales}}
                    <a href="{{url}}" class="dropdown-item" dir="{{direction}}" rel="nofollow"
                        role="menuitem">{{name}}</a>{{/each}}
                </div>
            </div>{{/if}}
            {{#if signed_in}}
            <div class="dropdown">
                <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton"
                    data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                    {{user_avatar class="user-avatar"}}
                    {{user_name}}
                </button>
                <div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
                    <a href="#" class="dropdown-item">{{link "my_activities" role="menuitem"}}</a>
                    <a href="#" class="dropdown-item">{{my_profile role="menuitem"}}</a>
                    <a href="#" class="dropdown-item password-item">{{change_password role="menuitem"}}</a>
                    <a href="#" class="dropdown-item">{{link "sign_out" role="menuitem"}}</a>
                </div>
            </div>

            {{else}}
            <div class="sign-in-div">
                {{#link "sign_in" class="sign-in"}}
                {{t 'sign_in'}}
                {{/link}}
            </div>
            {{/if}}


        </div>

    </div>


</nav>
