HTML5 Jobs

Hi, I'm looking for someone to help continue development on an existing web application. The project was originally built in React and we've been migrating it to Next.js. Unfortunately, the previous developer couldn't finish the migration before leaving the project, so there are still a number of incomplete areas that need to be cleaned up. Nothing is in terrible shape, but there are quite a few loose ends. Some UI sections disappeared during the migration, a few pages aren't behaving as expected, and the overall user experience could use another round of polishing. I'm looking for someone who enjoys working on an existing product rather than starting from scratch. Some of the things we'll probably work on together include: Restoring UI components that w...

I’m finishing up a real-time chat app that communicates through WebSockets and lives on Vercel. The missing piece is a clean, lightweight landing page where new users can create an account with their email and a password. Here’s what I need: • A responsive page that loads quickly on Vercel and matches the minimalist look of the existing site. • A single form that captures email + password, validates on the client side, then hits my existing API endpoint for registration. • Proper error and success handling so users immediately know whether the account was created. • Seamless redirect to the chat dashboard once registration succeeds. Tech stack is flexible as long as it plays nicely with Vercel and my WebSocket-based backend; or plain React are...

I manage a steady flow of small-business sites whose single goal is to generate qualified leads. I need a developer who is fully at home with , Tailwind CSS, Supabase, Vercel and GitHub to translate the design references or Figma files I supply into clean, production-ready code. Every project is white-label, so you will never communicate directly with the client; you hand the work to me, I handle everything else. Code quality, reusability and mobile responsiveness are non-negotiable. A lightweight contact form (Supabase-backed or another simple solution you prefer) plus any basic third-party integrations must be included and working on hand-off. Final deployment should be live on my Vercel account, with the full repository pushed to GitHub. For the typical 5-page build, let me know: &b...

Front-End Developer Needed to Reproduce Seven-Page Website From Final Visual Mockups I have completed the creative direction for a seven-page informational website. Every page has a final visual mockup, final written copy, approved imagery, one official logo, and specified fonts and type sizes. This is not a design project. I am not seeking creative reinterpretation, alternate layouts, substituted graphics, revised typography, or independent design decisions. The developer’s job is to reproduce the supplied pages accurately and consistently in clean, responsive HTML and CSS. Project Scope Build seven responsive website pages that match the supplied visual mockups as closely as reasonably possible across modern desktop, tablet, and mobile browsers. The completed webs...

I’m building a fully Arabic, right-to-left learning-management website that will let me host, manage, and sell video-based courses.

I need one-page site that funnel visitors straight to my main website. Each page must be static, lightweight, and quick to load, yet lively enough to grab attention at first glance. My brief (attached) sets out the exact copy, images, video snippets, and infographics I will supply. Your job is to blend that mix of content into a creative, colorful layout that drives a single, clear call-to-action for lead generation. Responsive behaviour across mobile, tablet, and desktop is essential, and the final code should be clean HTML5/CSS3 with any lightweight JavaScript kept to a minimum so the pages stay truly static. Deliverables • 5 fully responsive HTML/CSS pages, each in its own folder with all linked assets • Optimised images, embedded videos/infographics, and open-graph/...

I need assistance connecting a predictions market (Coinbase/Kalshi) to my existing auto trading program, which is built using JavaScript, HTML, and CSS.

Ideal Skills and Experience: - Experience with Coinbase/Kalshi APIs - Proficiency in JavaScript, HTML, and CSS - Familiarity with auto trading systems - Strong problem-solving skills

Task Description: Walk & Wonder - AI-Powered Interactive Storytelling Map Project Overview We are looking for an experienced full-stack developer (or team) to build a dynamic, mobile-responsive web application called "Walk & Wonder". This project combines interactive mapping with AI-generated storytelling to encourage families to walk and explore their local environment.

Based on these inputs, an AI (e.g., OpenAI API, Claude, or Gemini) will generate a personalized story and a safe walking route connecting the points. The project requires a modular approach, as we want to price and develop features iteratively. Core Require...

I’m putting together a fully-fledged, advanced-level eLearning course and need someone who can record and hand over polished video lessons—think crisp 1080p (or better) screen capture, studio-clear English narration, and legible code zooms. The curriculum must move well beyond basics, weaving JavaScript and TypeScript fundamentals into deep dives on React, Redux, and Zustand. Here’s the ground I want covered: modern React patterns with hooks, Context API, lifecycle know-how for class components, and concrete performance-tuning techniques; Redux Toolkit and Zustand for state management in real-world, production-style examples; plus any ancillary tooling you naturally reach for (Webpack/Vite, ESLint, testing libraries, etc.) as long as it serves the lesson.

Hello Sir, lets continue the project. place bid to discuss more in chat

I need a standalone Windows desktop application whose sole focus is reporting and analytics. The interface must be built with clean, responsive HTML5 and CSS3; you are free to add JavaScript for interactivity, data manipulation, and charting if that streamlines the build. Core scope • Present data in clear tables, dashboards, and printable reports. • Allow users to filter, sort, and export results (PDF or Excel preferred). • Run entirely on Windows without requiring a browser—packaging with Electron, Tauri, or a similar framework is fine as long as the final installer is simple for end-users. What I will provide Datasets, report requirements, and any branding assets you might need. Configuration details (file paths, endpoints, credentials) will be supplie...

Title: Established Indian Web Development Company Required for Long-Term PHP Partnership We are an established German web and digital production company looking for a professional and experienced web development company based in India for a long-term partnership.

I’m ready to take my personal recipe collection online and need a developer who can turn the vision into a polished, minimalist website that lets my dishes be the star of the show. The primary goal is straightforward: the site must elegantly showcase only my own recipes—no outside aggregation, no user-generated uploads. Design direction Think airy white space, subtle typography, and an uncluttered layout that guides visitors directly to each recipe. Responsive behavior is essential; the pages should feel just as refined on a phone as on a desktop. Core requirements • A lightweight, fast-loading front end with clean code (HTML5, CSS3, JavaScript or a preferred framework). • Simple, intuitive navigation that organizes recipes by category and allows quick filteri...

I need a brand-new mobile application built for both iOS and Android, delivered as a single, cohesive code-base that feels completely native on each platform. All core features and user flows are already mapped out on my side; I will pass along wireframes, a detailed functional specification, and brand assets as soon as we kick off. The job covers the full life-cycle: refining the technical architecture, crafting a polished UI, coding the front-end and any required back-end services, thorough QA on real devices, and finally shepherding the builds through App Store and Google Play submission. A modern cross-platform stack such as Flutter, React Native, or another comparable solution is perfectly acceptable—feel free to advocate for the approach you believe will give the smoothest per...

All the models, sounds, and visual assets for MorphUp are already live in the place linked here: What I still need is the Lua scripting that brings everything to life plus a handful of minimalistic in-engine animations. Scope • Character controls only: movement, interaction with existing morphs, and any client-side feedback that makes the controls feel smooth and responsive. • A few short, minimalistic animations to cover idle, start/stop movement, and morph transition states. The models are rigged; I simply need these keyed, tested, and hooked into the scripts. I will provide full team-create access, the current place file, and a concise task checklist. Once the new controls and animations are merged, I expect a quick play-test session together to verify that the inputs...

The product page of my site has a broken grid: cards that should sit in neat rows are scattering into uneven columns, leaving awkward gaps and pushing some items far right or far below the fold. The issue is strictly a layout problem—styling and responsiveness elsewhere are fine—so the fix should focus on the underlying HTML structure and CSS grid/flex rules that govern this page. You’ll dive into the existing markup, identify why the grid is collapsing, and apply clean, standards-compliant code to restore consistent alignment across modern browsers. A quick walkthrough of what I expect: • Diagnose the root cause in the current HTML/CSS. • Update or rewrite the grid/flex declarations so every product card lines up evenly on desktop and mobile breakpoints. ...

I need four production-ready HTML/CSS/JS template sets that walk a borrower through a completely self-service digital loan journey. Each set must feel modern and minimalistic, echoing the “no-friction” flow you see on ICICI, HDFC and other leading Indian bank sites, yet remain clean enough for us to re-skin for different brands later. Scope of the journey • Step 1 – real-time loan eligibility check • Step 2 – full loan application form (We do not require status-tracking screens in this delivery.) Core requirements • Four visually distinct template versions, all responsive across desktop, mobile and tablet. • Central theme file (variables for color, typography, spacing) so our engineers can swap branding in one place. • Vanilla ...

I need the fluid, card-to-card vertical scroll that TikTok popularised added to my existing Angular web app. Each item in the feed should occupy the full viewport, lock the background while it’s onscreen, and snap cleanly to the next item with a flick or mouse-wheel action. Performance must stay silky on mobile and desktop browsers alike, so lazy loading, virtualisation, and touch-friendly event handling are essential. The current codebase is Angular 14 with standard routing and NgRx for state. You can extend what is there or introduce a lightweight helper library—whatever keeps bundle size lean and Core Web Vitals green. CSS needs to remain customisable because the product team will skin the feed later. Deliverable: • A reusable Angular component (or module) wired into ...

I’m kicking off a green-field web application for D Daya AI and need a full-stack partner who can take the idea from wireframe to deployable product. The build starts from scratch, so you’ll own both the front-end experience and the back-end logic.

Deliverables • ...

My static HTML site looks great on desktop but stumbles on phones, and I need it polished for an upcoming user-testing round. The focus is threefold: • Mobile responsiveness – The navigation menu, all image / gallery components, and every form or input field must render and behave flawlessly on common mobile breakpoints. • Code & visual declutter – Strip out unused scripts and styles, remove any duplicate content, and trim excessive page elements so the pages load fast and remain easy to maintain. • Scalable content sections – Re-work the current markup so I can drop in new blog/news items and additional media-gallery entries via simple placeholders, without introducing a full CMS. Everything is plain HTML, CSS and a little vanilla JavaScript right ...

I need help solving 2 coding challenges as part of an interview process, in Javascript and nodejs

I want a small, high-impact site that immediately communicates my personal brand. The core structure is simple—homepage, about section, contact form, and a strip of social-media icons—but every element has to look professional, load fast, and feel perfectly at home on any screen size. Clean typography, restrained color, and smooth transitions are far more important to me than flashy effects. Responsiveness is non-negotiable, so please treat mobile-first practices, lazy-loading images, and concise HTML5/CSS3 as baseline. If you prefer a framework such as Bootstrap or Tailwind that’s fine, as long as the final CSS stays lightweight. Likewise, you can build on WordPress, a headless CMS, or plain code; what matters is easy content editing and page speeds that keep Core Web V...
