Javascript 如何将旋转木马居中？

我在这里读了一些建议，并且已经试过了，没有一个对我有用。所以我把代码放在这里，看看是否有人能给我指出正确的方向

我想把旋转木马放在中间

我希望在旋转木马中有一个单独的包含文本的容器，我希望该容器看起来有点褪色，可以使用不透明度元素或RGB（0,0,0,0.4）。。元素

HTML-

* {
    margin: 0;
    padding: 0;

body {
    font-family: Calibri, sans-serif;
}
.background-wrap {
    position: fixed;
    width: 100%;
    height: 100%;
    overflow: hidden;

/* Since positioning the image, we need to help out the caption */
.carousel-caption {

/* Declare heights because of positioning of img element */
.carousel .item {

我不知道如何在这里发布HTMLs而不会出现间距错误，所以我在codepen中打开了一支笔：

CSS-

* {
    margin: 0;
    padding: 0;
}
body {
    font-family: Calibri, sans-serif;
}
.background-wrap {
    position: fixed;
    width: 100%;
    height: 100%;
    overflow: hidden;
    top: 0;
    left: 0;
    z-index: -1000;
}
#video-bg-elem {
    top: 0;
    left: 0;
    height: 100%;
    width: 100%;
    object-fit: cover;
}
.navbar{
    background-color: RGBA(0,0,0,0.2) !important;
}
#brand-image{
    height: 100px;
}
a.navbar-brand{
    position: relative;
}
.navbar-nav > li{
    margin-left:10px;
    padding: 33px 10px;
  }
.navbar-nav > li > a{
    text-decoration: none;
    font-size: 2vh;
    font-size: 2.3vw;
    font-family: 'Freestyle Script';
    font-weight: 900;
    color: rgb(210, 21, 84) !important;
    padding-bottom: 0.2%;
    display: block;
}
.navbar-nav > li:hover,
.navbar-nav > li:focus {
    background-color: RGBA(0,0,0,0.4) !important;
    transition: .9s;
}
.navbar-nav > .active > a,
.navbar-nav > .active > a:hover,
.navbar-nav > .active > a:focus {
    background-color: RGBA(0.0..0.4) !important;
}
.content {
    position: absolute;
    width: 100%;
    min-height: 100%;
}
.content h1 {
    text-align: center;
    font-size: 65px;
    text-transform: uppercase;
    font-weight: 300;
    color: #fff;
    margin-top: 5%;
    margin-bottom: 10px;
}
.content p {
    text-align: center;
    font-size: 20px;
    letter-spacing: 3px;
    color: #aaa;
}
.navbar-expand-lg .navbar-collapse {
    margin:-7px;
}
/* CUSTOMIZE THE CAROUSEL
-------------------------------------------------- */
/* Carousel base class */
.carousel {
    width: 1200px;
    margin-bottom: 480px;
}

/* Since positioning the image, we need to help out the caption */
.carousel-caption {
    z-index: 10;
}

/* Declare heights because of positioning of img element */
.carousel .item {
    height: 500px;
    background-color: #777;
}

.carousel-inner > .item > img {
    position: absolute;
    top: 0;
    left: 0;
    min-width: 100%;
    height: 480px;
}

将此规则应用于您的课堂：

.carousel {
    max-width: 1200px;
    width: auto;
    margin: 0 auto 0 auto;
    text-align: center;
}

嗨@Jaziel_Inc.你太棒了。成功了。非常感谢。你能告诉我怎么把旋转木马弄小一点吗？因为1200太大了，我需要屏幕两侧的边距。嘿，如果你想让旋转木马变小，只需更改“最大宽度”属性，输入你想要的大小，我将1200px作为示例，但你可以更改为你想要的大小，试试看，我不是专家，但我认为是可行的。@ MahiyaHawk，如果这个答案已经解决了你的问题，请考虑点击复选标记。这向更广泛的社区表明，你已经找到了一个解决方案，并给回答者和你自己带来了一些声誉。没有义务这样做。
