Hello, world!

# Bootstrap-Blackbox Quick Start A basic HTML file should look like this: ```html Hello, world! ``` That's all. The page will automatically transition to Dark Mode when the users sets their OS to Dark Mode. > This variant is essentially the same as the nightshade variant, but instead of using a HTML tag class, it uses a HTML tag data attribute; `data-bs-color-scheme`. Refer to the [Bootstrap 5 Docs](https://getbootstrap.com/docs/5.1/getting-started/introduction/#starter-template) for more help. *** If you wish to add a Dark Mode Toggle button, simply add the following: ```html ``` Refer to the [`darkmode.js` Reference](darkmode.js.md) for more on the `darkmode` JavaScript object.
