Bug:dark主题，gitalk输入框的文字也会变成白色，导致无法看清输入内容。

gitalk输入字体的颜色为rgba(255,255,255,0.7)，输入框背景色为#fbfbfb，导致无法看清输入内容。

Bug fixed, I'll make a pull request to gitalk.

@kitian616 When I used the Google custom search engine under the dark theme, I faced the same problem. I could see the keywords that I typed.

By the way, I used the custom search engine to search some words in my blog but I didn't succeed, do I need to wait for a few days until Google has recorded my GitHub pages? Now I have switched back the default search engine. Thanks.

这个问题貌似没有完全解决，dark主题下gitalk评论的标题仍然是白色文字，如下图所示

选中之后可以看到文字是存在的
