Can an HTML element have arbitrary attributes?

Solution

Yes, you can have custom attributes:

<div imMakingUpAnAttribute="whatever"></div>

To differentiate between element and custom attributes, a good practice is to prefix it with `data-`.

<div data-imMakingUpAnAttribute="whatever"></div>

Problem

Can an HTML element be assigned arbitrary attributes? For example: ``` <div imMakingUpAnAttribute="whatever"></div> ```
