Lines 12-20 are getting there: 

- Should `sets_div_class_value` be called in both the `form-group` divs or in `f.text_field` and `f.text_area`? 
- HTML's `class` attribute ought to be surrounded by quotes, e.g. <h1 class="headline fancy">. Can you fix line 13 to make sure this rule is obeyed?

Once you've taken care of those, make a commit to the branch, and push it to GitHub. Only after that (in this branch), then try to spend a few minutes coming up with a new name for `sets_div_class_value` that captures the essence of what that method is doing.

For the new method name, if a developer new to this project was reading lines 12-20 of this template for the first time, we'd like them to be able to make a good guess at what that helper method does to our HTML without them having to go look at the method's implementation in the helper.

If you can't decide on a single name, then message me with a few candidate names. If you can, then refactor the template and helper to use the new name and push the changes to the remote branch.
