无法修改iframe中的内容的DOM或样式。你***做的是链接到不同样式的iframe，因为twitter提供了明亮和黑暗的主题。

There's no way to modify the DOM or style of the content in an iframe. The best you can do is link to a different-styled iframe, as twitter offers both light and dark themes.

编辑：话虽如此， < a> 标记，可用于进一步自定义主题。尝试修改数据按钮， data-text-color 和 data-link-颜色参数！

That being said, there are several parameters in the <a> tag that can be used to customize the theme even further. Try modifying the data-button, data-text-color, and data-link-color parameters to your liking!
