我在超大tron的角落上有一个CSS色带。色带坐在超大tron上，但我想向上移动色带，但仍要安装在右角上。我摆弄了css类，但不确定到底要更改什么才能达到所需的最终结果。 Jumbotron是bootstrap 3-请注意。

我不太确定你的意思。
您是否要使色带轻轻触摸超长波管？
然后，您必须使用.ribbon-wrapper-green类的top和right属性。
像这样的东西？
.ribbon-wrapper-green {
width: 180px;
height: 172px;
overflow: hidden;
position: absolute;
top: 0px;
right: -3px;
}
