如何删除Bootstrap 4巨型机下的空白

Question

我在使用超长距伞时遇到问题，由于某些原因，空格出现在空白处，我不知道它是由于我的代码还是我在某个地方出错了。我已经待了两天了。我在bootstrap 4网站上复制了jumbotron的代码。我可以为此提供一些帮助。如您所见，图片下方会出现空白。

.container_fluid.one {
    background-size: cover;
    height: 100vh;
    background-color:  #43E8E4;
}
.nav-item {
    padding-right:20px;
    font-size: 18px;
}
.info h1 {
    margin-top: 170px;
    line-height: 50px;
}
.info p {
    font-size: 15px;
}
span {
    color: #fffc00;
}
 span .gold{
    color: #fffc00;
}
.info p {
    font-size: 18px;
}
.white {
    color: #fff;
}
.navbar-dark .navbar-nav .nav-link:focus, .navbar-dark .navbar-nav .nav-link:hover {
    color: #fffc00;
}
.leader {
    margin-top: 110px;
    width: 457px;
    height: 316px;
}
.down {
    margin-top: 60px;
}
.container_fluid.two {
    background-size: cover;
    min-height: 100vh;
    background-color:  #43E8E4;
}
.jumbotron {
    margin-top: 0px;
}

我必须在!important之后放置margin: 0px才能使其正常工作

.jumbotron {
margin-bottom: 0px!important;
}
