I’m ready to have a 15-page static website built that presents my company’s information clearly and professionally. The goal is purely informational, so there is no shopping cart or database work—just fast-loading, well-structured HTML, CSS and a touch of vanilla JavaScript where it genuinely adds value. The look I want is unmistakably professional and corporate: clean typography, balanced whitespace, and a colour palette that feels confident without being flashy. Every page should render crisply on desktop, tablet and mobile, so responsive layouts are essential.

My draft site lives at and, at the moment, it is little more than a landing page. The assignment is to turn that placeholder into a clean, fast-loading personal blog that I can maintain myself. Scope of work • Build a lightweight blog theme (HTML, CSS, JavaScript or a static-site generator such as Jekyll/Hugo is fine) that matches the existing colour palette yet feels modern and readable. • Add a newsletter sign-up form and connect it to a service such as Mailchimp or Sendinblue; the form must work on both desktop and mobile. • Set up an easy publishing workflow—Markdown files pushed to GitHub and automatically deployed to GitHub Pages is ideal, but I am open to a simple CMS layer if that keeps editing friction-free. • Optimise for SEO basics

My site looks perfect on desktop and tablet, yet several elements slide out of place on mobile screens. The issue is strictly a visual one: mis-aligned sections, buttons that drift, and text that refuses to center. No JavaScript bugs—just CSS/HTML that needs tightening for small viewports. I’ll give you repo or FTP access along with screenshots of the current problem and the desired positioning. All changes should be limited to the frontend codebase (mostly a handful of Sass files and a responsive utility class). Once finished, the pages must render correctly on common mobile breakpoints (320-414 px) without introducing regressions to larger devices.

I need help repairing a responsive glitch that only shows up on mobile phones. On the homepage the layout breaks—sections slip out of place, spacing collapses, and the overall flow looks nothing like the desktop or tablet versions, which both render perfectly.

My website is a completely custom build—pure HTML, CSS, and vanilla JavaScript—so there’s no CMS or plugin ecosystem to lean on. I now need a lightweight backend that can generate large batches of QR codes, assign a unique ID to each one, store the mapping, and expose the results so the front-end can fetch or embed them on demand. Here’s the flow I have in mind: 1. I upload or call an endpoint with the quantity (or a CSV of labels). 2. The backend creates the unique IDs, generates the corresponding QR images, and saves both the ID and destination URL in a small database or file store. 3. It returns a simple JSON (or downloadable ZIP) the front-end can consume to display, print, or download every QR. Deliverables • A runnable backend service (...
