如何解决更改主题Epub书对Epubjs-rn软件包中的某些HTML标签不起作用

我使用包 Epubjs-rn 在我的代码中显示Epub图书，我希望在代码中覆盖Book主题，但是某些HTML标签没有样式，我看到了我的HTML来源这本书，我发现如果样式中定义的某些参数没有覆盖，例如，body标签backgroud不变，或者li标签的颜色不变，因为这是在HTML中设置的

任何人都可以帮助我更改 Epubjs-rn

中该HTML文件的背景

我在React-native中的代码：

  themes={{
                        "custom_theme": {
                            "p": {
                                "background-color": "purple","font-size": "15px"
                            },"h1": {
                                "color": "red",},"li": {
                                "background-color": "yellow","color":"red","body": {
                                "background": "#ffff00",}
                        }
                    }}
                    theme="custom_theme"

Epub HTML：
