<img> 与地址栏一起使用

Question

我正在尝试为带有图像的标题制作轮播。我正在使用 BOOTSTRAP 4 作为框架来使轮播工作

 <div id="aboutMe" class="carousel slide pt-1 container-fluid" data-ride="carousel">
     <!-- Carousel indicators --> 
       <ul class="carousel-indicators">
          <li data-target="#" class="active"></li>
          <li data-target="#"></li>
          <li data-target="#"></li>
       </ul>
       <!-- slide --> 
         <div class="carousel-inner">
             <div class="carousel-item active">
                <img style="background-image:url(https://images.unsplash.com/photo-1506882741710-98761c574b48?ixlib=rb-0.3.5&ixid=eyJhcHBfaWQiOjEyMDd9&s=794de1f3a10ddf74c928e6cebd1aa55e&auto=format&fit=crop&w=1050&q=80)" alt="The Chicago Theater">
             </div>
          </div>
        </div>

我想要做的是让我的图像覆盖容器，并且随着容器变小或变大，图像会在轮播中调整大小

Answer 1

您将图像用作具有内联样式的背景图像。你应该像这样添加图像

.carousel-item img {
  width: 100% !important;
  height: 100vh !important;
}

    <li data-target="#aboutMe" data-slide-to="1"></li>
