Question

我已经看过很多关于此主题的堆栈溢出帖子，但是我没有找到关于我在这里看到的行为的任何信息。我的图像尺寸为300 x 300，并且看起来像是在轮播机上根本无法使用时，彼此堆叠在一起。显然也没有滑块出现。这是我的代码：

<!-- Images -->
            <div id="myCarousel" class="carousel slide" data-ride="carousel">

                <!-- Indicators -->
                <ul class="carousel-indicators">
                    <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
                    <li data-target="#myCarousel" data-slide-to="1"></li>
                    <li data-target="#myCarousel" data-slide-to="2"></li>
                </ul>

                <!-- Slides -->
                <div class="carousel-inner">
                    <div class="item active">
                        <img src="https://www.w3schools.com/bootstrap/ny.jpg" alt="Los Angeles" height="300px" width="300px">
                    </div>

                    <div class="item">
                        <img src="https://www.w3schools.com/bootstrap/chicago.jpg" alt="Chicago" height="300px" width="300px">
                    </div>

                    <div class="item">
                        <img src="https://www.w3schools.com/bootstrap/newyork.jpg" alt="New york" height="300px" width="300px">
                    </div>
                </div>

                <!-- Controls -->
                <a class="left carousel-control" href="#myCarousel" data-slide="prev">
                    <span class="glyphicon glyphicon-chevron-left"></span>
                    <span class="sr-only">Previous</span>
                </a>
                <a class="right carousel-control" href="#myCarousel" data-slide="next">
                    <span class="glyphicon glyphicon-chevron-right"></span>
                    <span class="sr-only">Next</span>
                </a>
            </div>

请注意，其余的引导程序运行正常。这是我正在使用的导入：

<script type="text/javascript" th:src="@{/webjars/jquery/3.3.1-1/jquery.min.js}"></script>
    <script type="text/javascript" th:src="@{/webjars/bootstrap/4.2.1/js/bootstrap.min.js}"></script>
    <link rel="stylesheet" th:href="@{/webjars/bootstrap/4.2.1/css/bootstrap.min.css}"/>

您使用的代码与this w3schools示例相同，该示例用于引导程序3！

我认为您需要this w3schools tutorial for bootstrap 4。

bootstrap 4轮播忽略，图像堆叠在彼此之上
