Attention

This extension is NOT FULLY TESTED, so it may not fully cover the theme styles, if you find something wrong (such as bright things in night mode), please report it in this issue, do not open new issue.

Usage

1. Merge night branch from imaegoo/hexo-theme-icarus into your icarus theme folder, or dowmload zip.
2. If you configured an image logo, you should prepare a logo for night mode, then apply them in themes/icarus/_config.yml.

   logo:
       light: /images/logo.png
       dark: /images/logo-dark.png

---

1. 把 night 分支（imaegoo/hexo-theme-icarus）合并到你的主题分支中。如果你不懂，并且你对主题没有自己修改，直接下载修改好压缩包。
2. 如果你的网站 LOGO 是图片，你可能需要准备一黑一白两个版本的 LOGO，并在主题 themes/icarus/_config.yml 中配置。

   logo:
       light: /images/logo.png
       dark: /images/logo-dark.png

Modify

If you want to customize your theme, you can modify night mode part in themes/icarus/source/css/style.styl.
