I need a clean, modern single-page site built with plain HTML5 and CSS3. The focus is a well-structured Home page that adapts smoothly from mobile to desktop, using fluid grids or flexbox and sensible media queries. I will supply the color scheme so you can weave it consistently through headings, buttons, and backgrounds. Because this is a beginner-level project, the build should stay lightweight—no frameworks, just semantic markup and neatly organized styles in a separate stylesheet. Code comments are welcome where logic might not be obvious. Deliverables • index.html with responsive layout • style.css reflecting my color palette • Any asset files (images, icons) neatly referenced • Quick preview or link so I can test on phone and desktop If you can turn this around quickly while keeping the code easy to read and extend, let’s get started.
