rmarkdown 中的着色选项卡

考虑以下 rmarkdown 文件:

consider the following rmarkdown file:

---
title: "tab colors"
output: 
  html_document:
    self_contained: no
---
<style>
.nav>li>a {
    position: relative;
    display: block;
    padding: 10px 15px;
    color: #990000;
}
.nav-pills>li.active>a, .nav-pills>li.active>a:hover, .nav-pills>li.active>a:focus {
    color: #ffffff;
    background-color: #990000;
}
</style>


#{.tabset .tabset-fade .tabset-pills}

##Tab red

Tab red

##Tab green

Tab green

我可以通过在开始时添加一些 css 来更改所有选项卡的颜色.但是，我希望第二个标签(标签绿色)具有不同的颜色.

I was able to change the color of all tabs by adding some css in the beginning. However, I would like the second tab (tab green) to have a different color.

我进行了一些实验，并尝试通过手动添加一些 html 标记来为第二部分创建一个不同的 html 类

I experimented a little bit and tried to create a different html-class for the second section by manually adding some html tag like

<a_green role="tab" data-toggle="tab" href="#tab-green" aria-controls="tab-green">tab green</a_green>

但这并没有达到预期的效果.

But this did not had the desired effect.

有人可以帮我吗?
