body {

#myCarousel{
position:absolute;
top:50%;
left:50%;
}
.active {
height:200px;
width:500px;
transform:translate(-200px,-200px);
}
.item {
height:200px;
}
.carousel-caption{
font-size:20px;
font-family:"fangsong";
color:red;
}color:red想让“标题1”显示为红色，为什么无效呢？

sample.css和bootstrap.min.css引入的顺序反了，两者都有
.carousel-caption。对于同一选择器，后引入的样式会覆盖之前的。
