emacs org export html:自定义段落与列表页边距

跟随 this 简单的解决方案,我用过 margin-left 和 margin-right 要使导出的HTML页面以更易于阅读的格式显示,两边都有较大的边距:

#+HTML_HEAD_EXTRA: <style>*{margin-left: 2em}*{margin-right: 2em}</style>

所以页面看起来像:

        This is a very long sentence as an 
        example of reading friendly large
        margins in the exported HTML document
        of my org file.

而不是:

This is a very long sentence as an example of not-reading friendly small margins
in the exported HTML document of my org file.

段落看起来确实更好。然而,现在的问题是利润率的增加会影响TOC和正文中的所有列表项。比如:

- List item 1
          - Subitem 1.1
          - Subitem 1.2
                   - Subsubitem 1.2.1
- List Item 2
          - Subitem 2.1
          - Subitem 2.2

我更愿意看到:

- List item 1
  - Subitem 1.1
  - Subitem 1.2
    - Subsubitem 1.2.1
- List Item 2
  - Subitem 2.1
  - Subitem 2.2

现在,是否可以只为文本段落设置自定义边距,而不影响列表?有什么好方法可以做到?
