我有以下 1 行 2 列的代码。然而，屏幕边缘有很多额外的空间。知道如何解决它吗？

<div class="row">
    <div class="col col-md-3">
        <div class="card h-100">
            <p class="card-body">This card on the left of the other two cards, with a fixed height and scrolling.</p>
        </div>
    </div>
    <div class="col col-md-9">
        <div class="card">
            <p class="card-body">How do you want to ask the question?<p>
        </div>
        <div class="card">
            <p class="card-body">How should students ask the question?</p>

只需删除带有类容器的 div。

<div class="row">
<div class="col col-md-3">
    <div class="card h-100">
        <p class="card-body">This card on the left of the other two cards, with a fixed height and scrolling.</p>
    </div>
</div>
<div class="col col-md-9">
    <div class="card">
        <p class="card-body">How do you want to ask the question?<p>
    </div>
    <div class="card">
        <p class="card-body">How should students ask the question?</p>
    </div>
</div>
