I have a simple one–page HTML splash site that needs a quick polish so it actually tells visitors who we are and lets them subscribe for updates. Here’s what I need: • Inject a short block of text and a couple of images in the existing layout without breaking the current responsive behaviour. • Drop in an email-newsletter signup (any lightweight solution is fine—Mailchimp embed, tiny PHP handler, etc.). It just has to collect addresses to a list I can export. • Replace the plain colour with an eye-catching background. I have no fixed style in mind, so feel free to suggest a modern, vintage, or bright look that complements the new content. Please keep the code clean (HTML5/CSS3, minimal JS) so I can maintain it myself later. When you’re done, send back the updated files and a brief note on any libraries or CDN links you added. If this sounds straightforward to you, let’s get it live today.
