Bulma is a CSS framework, meaning that the end result is simply a single `.css` file:

Because Bulma solely comprises CSS classes, the HTML code you write has no impact on the styling of your page. That's why `.input` exists as a class, so you can choose which `<input type="text">` elements you want to style.

Bulma only styles generic tags directly twice:

- `generic.sass` to define a basic style for your page
- the `.content` class to use for any textual content, like WYSIWYG
