美好的一天，我＆＃39;使用bootstrap 3并试图让我的bootstrap轮播在中心。这是我到目前为止尝试的脚本。

但是，我的剧本在我的Caraousel上面仍然在屏幕的左边。然后我尝试用谷歌搜索，我发现这个https://stackoverflow.com/questions/19582340/make-bootstraps-carousel-both-center-and-responsive但仍然没有帮助。有解决方案吗提前谢谢，抱歉我的英文不好

答案 0 :(得分：2)

您只是缺少一行代码：

.carousel {
  margin: 0 auto;
}

轮播是<div>，它是 block-level 元素，因此您可以通过将水平边距设置为auto来集中它。在将水平边距设置为margin: 0 auto时，速记0将上边距和下边距设置为auto。

这是一个有效的示例（运行代码段后点击“完整页面”）：

.navbar.transparent.navbar-inverse .navbar-inner {
  border-width: 0px;
  -webkit-box-shadow: 0px 0px;
  box-shadow: 0px 0px;
  background-color: rgba(0, 0, 0, 0.0);
  background-image: -webkit-gradient(linear, 50.00% 0.00%, 50.00% 100.00%, color-stop( 0%, rgba(0, 0, 0, 0.00)), color-stop( 100%, rgba(0, 0, 0, 0.00)));
  background-image: -webkit-linear-gradient(270deg, rgba(0, 0, 0, 0.00) 0%, rgba(0, 0, 0, 0.00) 100%);
  background-image: linear-gradient(180deg, rgba(0, 0, 0, 0.00) 0%, rgba(0, 0, 0, 0.00) 100%);
}

#Intro {
  display: inline-block;
}

#topnavbar {
  top: 20px;
}

.carousel {
  width: 600px;
  height: 400px;
  margin: 0 auto;
}

.carousel-inner>.item>img {
  margin: 0 auto;
}

div.c-wrapper {
  width: 100%;
  /* for example */
  margin: auto;
}

.carousel-inner>.item>img,
.carousel-inner>.item>a>img {
  width: 100%;
  /* use this, or not */
  margin: auto;
}

.container {
  border: 1px;
}
