[Feat]: Add dark mode.

I'm having difficulty finding the "text" and "button" on the website. Would it be possible to add a dark mode?

I'm having trouble locating the "text" and "button" on the website. It would be immensely helpful if we could incorporate a dark mode on the webpage. Would you consider implementing this feature?
