Add description field?

Trying to find a way to add a description above a set of fields. When I do it via the “html before field”, it makes the following fields on the left move down, but not their counterparts on the right hand side of the form.
Basically, I need a way to label a group of fields below. For example:

List some events you’ve participated in:
Activity {text area} Grades: 9(checkbox) 10(checkbox) 11(etc)
Activity {text area} Grades: 9(checkbox) 10(checkbox) 11(etc)
Activity {text area} Grades: 9(checkbox) 10(checkbox) 11(etc)

The “List some events you’ve participated in” is the part I need to just be prior to the following fields. Like perhaps a “description” field set, where no text box is required.

I did attempt to do this using fieldset{boxopen} and fieldset{boxclose}, but then it wouldn’t align everything anymore. Can this just be fixed with CSS? If so, then this may be a viable option.

Thank you!
