html - CSS 和 R Markdown (bookdown)。如何在不更改整体模板的情况下使用 CSS 构建 css 框？

Question

好吧，我认为这可能是一个非常幼稚的问题，但我没有找到任何有用的解决方案。我有一个用于教学统计的“R markdown”，我在其中使用 CSS 文件为我所有的问题自定义一些外观。我已经导入了这个 CSS file from here这非常酷，因为我可以轻松创建一个问题框，例如这个:

但是，现在，在我的 R Markdown 文件中，每次输入“1.”“2.”等时，它都会变成一个问题框。
如何修改 CSS 以防止将我的所有列表转换为“问题框”？

谢谢。

请检查下面的 CSS 文件:

body {
    counter-reset: li; /* initialize counter named li */
}

h1 {
    font-family:Arial, Helvetica, sans-serif;
    font-weight:bold;
}

h2 {
    font-family:Arial, Helvetica, sans-serif;
    font-weight:bold;
    margin-top: 24px;
}

ol {
    margin-left:0; /* Remove the default left margin */
    padding-left:0; /* Remove the default left padding */
}
ol > li {
    position:relative; /* Create a positioning context */
    margin:0 0 10px 2em; /* Give each list item a left margin to make room for the numbers */
    padding:10px 80px; /* Add some spacing around the content */
    list-style:none; /* Disable the normal item numbering */
    border-top:2px solid #317EAC;
    background:rgba(49, 126, 172, 0.1);
}
ol > li:before {
    content:"Exercise " counter(li); /* Use the counter as content */
    counter-increment:li; /* Increment the counter by 1 */
    /* Position and style the number */
    position:absolute;
    top:-2px;
    left:-2em;
    -moz-box-sizing:border-box;
    -webkit-box-sizing:border-box;
    box-sizing:border-box;
    width:7em;
    /* Some space between the number and the content in browsers that support
       generated content but not positioning it (Camino 2 is one example) */
    margin-right:8px;
    padding:4px;
    border-top:2px solid #317EAC;
    color:#fff;
    background:#317EAC;
    font-weight:bold;
    font-family:"Helvetica Neue", Arial, sans-serif;
    text-align:center;
}
li ol,
li ul {margin-top:6px;}
ol ol li:last-child {margin-bottom:0;}

.oyo ul {
    list-style-type:decimal;
}

hr {
    border: 1px solid #357FAA;
}

div#boxedtext {
    background-color: rgba(86, 155, 189, 0.2);
    padding: 20px;
    margin-bottom: 20px;
    font-size: 10pt;
}

div#template {
    margin-top: 30px;
    margin-bottom: 30px;
    color: #808080;
    border:1px solid #808080;
    padding: 10px 10px;
    background-color: rgba(128, 128, 128, 0.2);
    border-radius: 5px;
}

div#license { 
    margin-top: 30px;
    margin-bottom: 30px;
    color: #4C721D;
    border:1px solid #4C721D;
    padding: 10px 10px;
    background-color: rgba(76, 114, 29, 0.2);
    border-radius: 5px;
}

如果有人遇到同样的问题，这就是解决方案。

在 CSS 文件中，以特定字符串(如下)开始命令，然后在 Markdown 上使用 div 符号。如:

<div class="question">
1. My first question 
1. My second question
</div>

  /* -----------Question counter ---------*/

  body {
    counter-reset: li;
  }
 h1 {
    font-family:Arial, Helvetica, sans-serif;
    font-weight:bold;
 }

 h2 {
    font-family:Arial, Helvetica, sans-serif;
    font-weight:bold;
    margin-top: 24px;
 }
  .question ol {
    margin-left:0; /* Remove the default left margin */
    padding-left:0; /* Remove the default left padding */
  }

  .question ol>li {
    position:relative; /* Create a positioning context */
    margin:0 0 10px 2em; /* Give each list item a left margin to make room for the numbers */
    padding:10px 80px; /* Add some spacing around the content */
    list-style:none; /* Disable the normal item numbering */
    border-top:2px solid #317EAC;
    background:rgba(49, 126, 172, 0.1);
  }

  .question ol>li:before,
  .question ol>p>li:before {
    content:"Questão " counter(li); /* Use the counter as content */
    counter-increment:li; /* Increment the counter by 1 */
    /* Position and style the number */
    position:absolute;
    top:-2px;
    left:-2em;
    -moz-box-sizing:border-box;
    -webkit-box-sizing:border-box;
    box-sizing:border-box;
    width:7em;
    /* Some space between the number and the content in browsers that support
       generated content but not positioning it (Camino 2 is one example) */
    margin-right:8px;
    padding:4px;
    border-top:2px solid #317EAC;
    color:#fff;
    background:#317EAC;
    font-weight:bold;
    font-family:"Helvetica Neue", Arial, sans-serif;
    text-align:center;
  }

  .question ol ol {
    counter-reset: subitem;
  }

  .question li ol,
  .question li ul {margin-top:6px;}
  .question ol ol li:last-child {margin-bottom:0;}
