I need to solve my confusion

the second project challenge is survey from. but I want to know that. how the survey is look like , is it with a database or simply a front -end from.

just front-end
the Survey Form is in the HTML-CSS (Responsive Web Design) certification

if you want you can also build the backend but it would go outside of the scope of it

to get getter once you finish a project you can ask for peer review in the #project-feedback subforum , so people can look at your projects and give you advices on how to get better
