html - 如何将 Content DIV 放在 bootstrap carousel 上并使其响应？

Question

我想在大屏幕和桌面屏幕的 Bootstrap 轮播中放置一个内容 DIV。请参阅下图以了解您的理解。

在手机和标签页中应该是这样的——

我不确定如何使用 bootstrap 3 创建此布局。希望有人可以帮助我。

这是我当前的标记:

  <div style="width: 300px; height: 500px; background: red;"></div>

</main>

演示:https://jsbin.com/lufoli

在每个中断宽度处镜像 .container 的大小，这就是名为“.red”的父级。将 .red 绝对定位元素居中，方法是使用 left: 50%，然后在每个断点处使用宽度为 1/2 的负边距。然后在该父级中添加表单/div，并在最小宽度处刷新它。

CSS

.slide-wrapper {
    position: relative
}

.red {
    padding-right: 15px;
    padding-left: 15px;
    margin-right: auto;
    margin-left: auto;
}
.red-content {
    width: 100%;
    height: 300px;
    background: red;
    color: #fff;
}
@media (min-width: 768px) { 
    .carousel-caption {
        text-align: left;
        padding-right: 300px;
    }
    .red {
        width: 750px;
        position: absolute;
        left: 50%;
        top: 0;
        bottom: 0;
        padding: 20px 0;
        margin-left: -375px;
    }
    .red-content {
        width: 300px;
        float: right;
        height: 100%;
        background: red;
        color: #fff;
        margin-right:15px; /* width of .container gutter */
    }
}
@media (min-width: 992px) { 
    .red {
        width: 970px;
        margin-left: -485px;
    }
}
@media (min-width: 1200px) { 
    .red {
        width: 1170px;
        margin-left: -585px;
    }
}

/* MISC */
#homepage-feature .item {
    overflow: hidden;
    height: 400px;
    background-color: transparent;
    background-size: cover;
}
#homepage-feature > .carousel-control {
    width: 30px;
    font-size: 40px;
    color: #fff;
    text-shadow: none;
    filter: none;
    opacity: 1;
}
#homepage-feature > .carousel-control span {
    position: absolute;
    top: 50%;
    margin-top: -30px;
    width: 100%;
    text-align: center;
    display: block;
}
