Question

我想创建一个固定背景的轮播。仅文本应更改。

我试图在每张幻灯片中放置相同的背景图像，但是我不喜欢切换动画。我认为最好只更改文本。

我的代码：

<div id="myCarousel" class="carousel slide" data-ride="carousel">
            <ol 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>
            </ol>
            <div class="carousel-inner">
                <div class="carousel-item active">
                <img class="first-slide" src="img/earth1.jpg" alt="First slide">
                    <div class="container">
                        <div class="carousel-caption text-left">
                            <h1>TEXT 1</h1>
                            <p id="screen"></p>
                            <p>text1</p>
                        </div>
                    </div>
                </div>
                <div class="carousel-item">
                    <img class="second-slide" src="img/earth1.jpg" alt="Second slide">
                    <div class="container">
                        <div class="carousel-caption">
                            <h1>TEXT 2</h1>
                            <p id="screen"></p>
                            <p>text2</p>
                        </div>
                    </div>
                </div>
                <div class="carousel-item">
                    <img class="third-slide" src="img/earth1.jpg" alt="Third slide">
                    <div class="container">
                        <div class="carousel-caption text-right">
                            <h1>TEXT 3</h1>
                            <p id="screen"></p>
                            <p>text3</p>
                        </div>
                    </div>
                </div>
            </div>
            <a class="carousel-control-prev" href="#myCarousel" role="button" data-slide="prev">
            <span class="carousel-control-prev-icon" aria-hidden="true"></span>
            <span class="sr-only">Previous</span>
            </a>
            <a class="carousel-control-next" href="#myCarousel" role="button" data-slide="next">
            <span class="carousel-control-next-icon" aria-hidden="true"></span>
            <span class="sr-only">Next</span>
            </a>
        </div>

我需要添加什么？

您应该尝试此操作：如下图所示，在轮播项目上方添加新的div，并根据需要设置背景图像，每张幻灯片上都可以得到相同的图像，只需在轮播项目中设置内容样式即可。您还可以将最小高度设置为背景图像，如下面的代码所示。

<div id="myCarousel" class="carousel slide" data-ride="carousel">
    <ol 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>
    </ol>
    <div class="carousel-inner">
        <div class="img" style="background-image: url('your image path');">
            <div class="carousel-item active">
                <img class="first-slide" src="img/earth1.jpg" alt="First slide">
                <div class="container">
                    <div class="carousel-caption text-left">
                        <h1>TEXT 1</h1>
                        <p id="screen"></p>
                        <p>text1</p>
                    </div>
                </div>
            </div>
            <div class="carousel-item">
                <img class="second-slide" src="img/earth1.jpg" alt="Second slide">
                <div class="container">
                    <div class="carousel-caption">
                        <h1>TEXT 2</h1>
                        <p id="screen"></p>
                        <p>text2</p>
                    </div>
                </div>
            </div>
            <div class="carousel-item">
                <img class="third-slide" src="img/earth1.jpg" alt="Third slide">
                <div class="container">
                    <div class="carousel-caption text-right">
                        <h1>TEXT 3</h1>
                        <p id="screen"></p>
                        <p>text3</p>
                    </div>
                </div>
            </div>
        </div>    
    </div>
    <a class="carousel-control-prev" href="#myCarousel" role="button" data-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
    </a>
    <a class="carousel-control-next" href="#myCarousel" role="button" data-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
    </a>
</div>

<style type="text/css">
    .img{
        background-repeat: no-repeat;
        background-size: cover;
        background-position: center;
        min-height:400px;
    }
</style>
