Question

我的图像处于设定的高度和宽度，因为它们的大小不同，所以我如何将旋转木马本身居中？

老实说，我不知道从哪里开始，因为我不知道如何在不搞砸引导样式的情况下做到这一点。任何帮助将不胜感激。

Answer 1

不是100％确定这是你想要的，但你可以看一下：http://www.bootply.com/t08I4ieD1s

基本上我所做的只是添加：margin：0 auto;到.carousel css

.carousel {
    width:640px;
    height:360px;
    margin: 0 auto;
}

并添加：

.carousel-indicators{
    width:auto;
    margin: 0 auto;
}

要在上方和下方添加空间，您需要更改顶部和底部边距。例如，您可以执行以下操作：

.carousel {
    width:640px;
    height:360px;
    margin: 100px auto 50px auto;
}

这将在旋转木马上方增加100px，在下方增加50px。请阅读此处：http://www.w3schools.com/cssref/pr_margin.asp了解更多信息。

Answer 2

尝试这个简单的解决方法：

您可以将bootstrap类.center-block用于此行

<div id="myCarousel" class="carousel center slide" data-ride="carousel">

添加课程后

<div id="myCarousel" class="carousel center-block center slide" data-ride="carousel">

bootstrap class .center-block使您的元素相对于其父元素水平居中。

我如何将bootstrap的旋转木马作为中心？不是图像，旋转木马本身
