python - Bootstrap 和 Flask - 如何让卡片堆叠在一起

问题描述

我正在制作一个航班预订 Web 应用程序，并在 HTML 页面中显示用户预订的航班，该页面位于这样的 for 循环中。

{% extends 'layout.html' %}
{% block content %}
    <div class="container">
        <div class="row welcome text-center">
            <div class="col-12">
                <h1 class="display-4">My Flights</h1>
            </div>
        </div>
    </div>
    {% for flight in flights %}
        <div class="container">
            <div class="row">
                <div class="col-sm">
                    <div class="card">
                        <div class="card-body">
                            <center><h5 class="card-title">Flight Number - {{ flight.flight_number }}</h5></center>
                            <center><h5 class="card-title">Fly Date - {{ flight.date }}</h5></center>
                        </div>
                        <ul class="list-group list-group-flush">
                            <center>
                                <li class="list-group-item">Fly Too - {{ flight.destination }}</li>
                            </center>
                            <center>
                                <li class="list-group-item">Fly From - {{ flight.fly_from }}</li>
                            </center>
                            <center>
                                <li class="list-group-item">Departure Time - {{ flight.time }}</li>
                            </center>
                        </ul>
                    </div>
                </div>
            </div>
        </div>
    {% endfor %}
{% endblock %}

这是从数据库中提取信息。

现在我在网页设计方面不是很好，所以任何帮助将不胜感激，谢谢，这里也是我用作每个页面基础的 layout.html。

解决方案

如果您使用 for 循环。有一些方法可以将卡片彼此相邻放置。这是我为示例所做的代码：

<div>
    <div class="card-deck">
        {% for post in posts %}
        <div class="card" style="min-width: 20rem; max-width: 22rem; margin-top: 5px;">
            <div class="card-body">
                <a href="{{ url_for('post', post_id=post.id) }}">
                    {{ post.details|safe }}
            </div>
        </div>
        </a>
        {% endfor %}
    </div>
</div>

style="min-width: 20rem; max-width: 22rem; margin-top: 5px;">有了这个你可以设置最小和最大宽度，然后我会自动设置它的位置。
