【问题描述】：

我的网站上有一个轮播，它不适合移动屏幕，并且图像超出了屏幕分辨率。当我检查浏览器的响应性时，它会正确显示。

下图是它在手机屏幕上的显示方式

当我在浏览器中检查响应时，它显示如下

这是我的代码

<div id="demo" class="carousel slide" data-ride="carousel">
    <!-- <ul class="carousel-indicators">
        <li data-target="#demo" data-slide-to="0" class="active"></li>
        <li data-target="#demo" data-slide-to="1"></li>
        <li data-target="#demo" data-slide-to="2"></li>
    </ul> -->
    <div class="carousel-inner">
        <div class="carousel-item active">
            <img src="images\home_banners\banner1.png" alt="top international schools in bangalore">
        </div>
        <div class="carousel-item">
            <img src="images\home_banners\banner2.png" alt="best cbse schools in bangalore south">
            <div class="carousel-caption">
            </div>
        </div>
        <div class="carousel-item">
            <img src="images\home_banners\banner3.png" alt="schools in bangalore icse">
            <div class="carousel-caption">
            </div>
        </div>
        <div class="carousel-item">
            <img src="images\home_banners\banner4.png" alt="best cbse schools in bangalore south">
            <div class="carousel-caption">
            </div>
        </div>
        <div class="carousel-item">
            <img src="images\home_banners\banner5.png" alt="schools in bangalore icse">
            <div class="carousel-caption">
            </div>
        </div>
    </div>
    <a class="carousel-control-prev" href="#demo" data-slide="prev">
        <span class="carousel-control-prev-icon"></span>
    </a>
    <a class="carousel-control-next" href="#demo" data-slide="next">
        <span class="carousel-control-next-icon"></span>
    </a>
</div>

这是我的CSS

#demo {
    top: 95px;
}

.carousel-inner img {
    /*width: auto !important;*/
    height: auto;
    width: 100% !important;
     /*height: 100%; */
    /* height: 500px; */
}

标签： html css twitter-bootstrap bootstrap-4

【解决方案1】：

在 img 标签中使用 img-fluid 类。

#demo {
  top: 95px;
}

.carousel-inner img {
  /*width: auto !important;*/
  height: auto;
  width: 100% !important;
  /*height: 100%; */
  /* height: 500px; */
}
