I have an existing HTML form that currently stacks every input in a single column. I’d like you to refactor the markup and CSS so the fields are divided equally into two clean, left-and-right columns. No extra borders, backgrounds, or decorative styling—just a straightforward, responsive split that keeps the form looking balanced on desktop and still flows sensibly on smaller screens. You will receive the current HTML file; please return the updated HTML and any accompanying CSS (inline or separate stylesheet, whichever you prefer) with clear comments so I can follow the changes. The finished form should render identically in modern browsers, with each column containing half of the original fields and maintaining the existing field order. If this sounds clear, let me know how soon you can deliver the revised files.
