I want a small, tidy web application that lets me whip up persuasive sales pages in minutes. My focus is on conversion-driven copy, so your focus will be pure programming: clean code, smooth UX, and a flexible template system I can expand later. Core idea The tool should take my copy blocks—headline, sub-headline, body, testimonials, guarantees, call-to-action—and render a responsive HTML/CSS page ready to publish. A simple front-end form or drag-and-drop interface is fine as long as it is intuitive. I am comfortable editing text, not code, so please keep any configuration options straightforward. Preferred stack JavaScript or Python are both acceptable; lightweight frameworks such as React with Node, or Flask/FastAPI on the back end, will work. Feel free to propose an alternative if it speeds development and keeps dependencies minimal. What you will deliver • Well-commented source code and a concise README explaining setup and deployment • One default theme plus clear instructions on how I can add new themes later • Mobile-first responsive layout that scores well on Google Lighthouse • Simple image upload or URL input for hero images and testimonial photos • A single-click export that produces a folder with ready-to-host HTML, CSS, JS, and asset files Acceptance criteria • The generated page must render correctly in the latest Chrome, Firefox, Safari, and Edge • All editable fields populat Do you want to create an effective sales page of product or service .
