解决方案

1-在 css 中给 body 一个 padding-top 和 navbar 一样的高度：

body { padding-top: 60px; }

2-最好使用 jQuery 来确定导航栏高度：

$('body').css('padding-top', $('.navbar').outerHeight());

3-如果您想使轮播+导航栏高度等于视图高度：

$('body').css('padding-top', $('.navbar').outerHeight());
var carouselHeight = $('body').height() - $('.navbar').outerHeight();
$('.carousel, .carousel .item, .carousel .carousel-inner').css('height', carouselHeight)
