css - 如何让两列垂直对齐？

Question

我有这个用于 Bootstrap 超大屏幕的代码，但是我希望左侧的列与 h1 和段落与右列中的图像垂直对齐，以便标题和段落与中心对齐的形象。你知道如何实现吗？

您还知道为什么超大屏幕不与导航栏对齐吗？ “标题”比左侧的导航栏图像更靠左，而且超大屏幕中的图像比导航栏的最后一项更靠右。你知道为什么吗？

我在这里有一个问题的演示:

        </a>
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent"
                aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">

Answer 1

在 .row 上使用 .align-items-center这将在 .row 中垂直对齐 .col-7 和 .col-5

<div class="row align-items-center">
    <div class="col-7">
        <h1 class="display-5 font-weight-bold text-dark">Title</h1>
        <p class="lead">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Molestias earum tempore, eveniet quis quae quo placeat ullam, maxime harum at corrupti, vel, cumque error pariatur veritatis doloribus libero quibusdam hic.</p>
    </div>

    <div class="col-5">
        <img src="https://via.placeholder.com/490" width="490" height="300">
    </div>
</div>

或者，您可以在 .col-7 上使用 .align-self-center这将仅垂直对齐 .col-7如果 .col-7 的高度恰好大于 .col-5，则 .col-5 将保留在 .row 的顶部，因为 .col-5 未在 .row 中垂直对齐

<div class="row">
    <div class="col-7 align-self-center">
        <h1 class="display-5 font-weight-bold text-dark">Title</h1>
        <p class="lead">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Molestias earum tempore, eveniet quis quae quo placeat ullam, maxime harum at corrupti, vel, cumque error pariatur veritatis doloribus libero quibusdam hic.</p>
    </div>

    <div class="col-5">
        <img src="https://via.placeholder.com/490" width="490" height="300">
    </div>
</div>
