Question

我假装让第一列固定，但是当我添加 position:fixed 时，列相互重叠，如何解决这个问题？

如果不可能，我想知道一个能给我一个的样本

侧边导航栏已修复并响应 bulma

据我了解，您的侧边栏在移动设备上消失了，对吗？
您是否尝试过从 aside 元素中删除 is-hidden-mobile 类？

<section class="main-content columns is-fullheight">
<aside class="column is-2 is-narrow-mobile is-fullheight section">
    <p class="menu-label is-hidden-touch">Header</p>
    <ul class="menu-list">
        <li>
            <a href="#go-first" class="is-active">CIT</a>
            <ul><li><a href="#">Items</a></li><li><a href="#">Items</a></li>
            </ul>
        </li>
        <li>
            <a href="#" class="is-active">Other</a>
            <ul>
                <li><a href="#">other</a></li>
            </ul>
        </li>
    </ul>
</aside>
<div class="container column is-10">
    <div class="section">
        <div class="card">
            <div class="card-header" id="go-first">
                <p class="card-header-title">CIT</p>
            </div>
            <div class="card-content">
                <div class="content">
                    header
                </div>
                <div class="columns">
                    <div class="column">
                        ...
                    </div>
                </div>
