Note: Starting May 1st, 2016, GitHub Pages will only support kramdown

The page build completed successfully, but returned the following warning:

You are currently using the 'redcarpet' Markdown engine, which will not be supported on GitHub Pages after May 1st. At that time, your site will use 'kramdown' for markdown rendering instead. To suppress this warning, remove the 'markdown' setting in your site's '_config.yml' file and confirm your site renders as expected. For more information, see https://help.github.com/articles/updating-your-markdown-processor-to-kramdown.

GitHub Pages was recently upgraded to Jekyll 3.0. It may help to confirm you're using the correct dependencies:

于是，方法

1. 直接推 html 到 github pages
2. 切换引擎 highlighter: rouge markdown: kramdown
3. 可能， css 也需要一些变动
