                        "The greatest glory in living lies not in never falling, but in rising every time 
    we fall."

        </Jumbotron>
}
 

I want to add carousel in the jumbotron. it compiles successfully but doesn't appear on the screen. it just shows arrows but not the content please help.

正如反应中的解释 bootstrap doc:

Carousels don’t automatically normalize slide dimensions. As such, you may need to use additional utilities or custom styles to appropriately size content. While carousels support previous/next controls and indicators, they’re not explicitly required. Add and customize as you see fit.

您需要在每个 <Carousel.Item> 中的 <Carousel.Caption> 之前添加一个 div(例如),如下所示:

 <Carousel.Item>
            <div className="d-block w-100" style={{ height: "400px" }} />
            <Carousel.Caption>
              <h3>
                "The greatest glory in living lies not in never falling, but in
                rising every time we fall."
              </h3>
              <p>-Nelson Mandela</p>
            </Carousel.Caption>
          </Carousel.Item>
