I have the HTML and CSS of a small site ready and now need the JavaScript layer that makes its forms truly work. The job is to create clean, modular ES6 code that validates user input in real time, prevents spam, and delivers the data asynchronously to an existing backend endpoint (Fetch API / AJAX). Deliverables • Vanilla JavaScript (or a very lightweight helper such as Axios) for form validation and submission • Field-level rules for text, e-mail, phone, checkboxes, select lists, and file uploads, with clear inline error messages • Accessible updates—proper ARIA attributes and keyboard-friendly focus handling • Graceful degradation when JavaScript is disabled • A concise README explaining how to drop the scripts into any page and adjust validation rules All markup and styling are set, so the only touchpoints will be the form elements themselves and the fetch URL I will provide. Please let me know your estimated turnaround time and reference any similar work so I can gauge fit quickly.
