Question

我正在使用ng-bootstrap为我的角度项目创建轮播。我成功地遵循了https://ng-bootstrap.github.io/#/components/carousel/examples所示的示例，现在屏幕中间有一个轮播。

我现在希望轮播占据整个屏幕宽度，而不是仅仅坐在中间。我该怎么做？

我尝试过在轮播中添加一个类，并像这样更改宽度：

组件HTML

<ngb-carousel *ngIf="images" class="myclass">
  <ng-template ngbSlide>
    <img [src]="images[0]" alt="Random first slide">
    <div class="carousel-caption">
      <h3>First slide label</h3>
      <p>Nulla vitae elit libero, a pharetra augue mollis interdum.</p>
    </div>
  </ng-template>
  <ng-template ngbSlide>
    <img [src]="images[1]" alt="Random second slide">
    <div class="carousel-caption">
      <h3>Second slide label</h3>
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
    </div>
  </ng-template>
  <ng-template ngbSlide>
    <img [src]="images[2]" alt="Random third slide">
    <div class="carousel-caption">
      <h3>Third slide label</h3>
      <p>Praesent commodo cursus magna, vel scelerisque nisl consectetur.</p>
    </div>
  </ng-template>
</ngb-carousel>

组件CSS

.myclass{
   width: 100%;
}

Answer 1

您必须将myclass设置为图像。您正在使用引导程序，因此可以改用w-100：

Try it online!

<ngb-carousel *ngIf="images">
  <ng-template ngbSlide>
    <img [src]="images[0]" alt="Random first slide" class="w-100">
    <div class="carousel-caption">
      <h3>First slide label</h3>
      <p>Nulla vitae elit libero, a pharetra augue mollis interdum.</p>
    </div>
  </ng-template>
  <ng-template ngbSlide>
    <img [src]="images[1]" alt="Random second slide" class="w-100">
    <div class="carousel-caption">
      <h3>Second slide label</h3>
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
    </div>
  </ng-template>
  <ng-template ngbSlide>
    <img [src]="images[2]" alt="Random third slide" >
    <div class="carousel-caption">
      <h3>Third slide label</h3>
      <p>Praesent commodo cursus magna, vel scelerisque nisl consectetur.</p>
    </div>
  </ng-template>
</ngb-carousel>

您可能还想使用object-fit:cover;

Answer 2

您也可以这样做。而不是使用！Important的w-100

<img [src]="images[0]" alt="Random first slide" width="100%">

Answer 3

在此处的html标签中直接添加示例：

<img [src]="images[0]" alt="Random first slide" class="mh-100" style="width: 100%; height: 50vh">
