Motivation

I have successfully fixed issue #866 for the caMicroscope project, which required centering the Sign Up button. As an applicant for Outreachy and someone passionate about contributing to the caMicroscope organization, I would greatly appreciate a review of my work to ensure it meets the project's standards. This experience has deepened my understanding of user-centered design and my ability to create intuitive user interfaces.
