You are on the right track, but for this challenge; you are targeting a `fieldset` element. The colon `:` acts kinda like a specifier for selecting classes. Pseudo-elements to be precise.
The `last-of-type` pseudo class does what it sounds like and selects the last element on the page.
More about the last-of-type pseudo class [here](https://developer.mozilla.org/en-US/docs/Web/CSS/:last-of-type).
Happy coding. 🙂
