Update Static HTML Website Content

I have a small, purely static site built with plain HTML and CSS. I’m looking for someone to jump in, clean up the code where needed, and handle two specific tasks:

• Refresh the copy in several spots and insert a brand-new body content section that I will supply in a Word doc.
• Make a couple of straightforward style tweaks so the new section blends seamlessly with the existing design.

No images or video work is required—this is strictly text-related. When you’re done I need the updated HTML and CSS files ready for me to drop straight onto the server, with all links and formatting intact and responsive behaviour unchanged. If that sounds like a quick win for you, let’s get started.
