A contact form stops working, a button does nothing, or a JavaScript error breaks one feature? Send me the page URL, the steps to reproduce it and what should happen.
For $35 I will investigate and fix one reproducible issue in an existing HTML/JavaScript website, then check the agreed flow and provide the changed files with a short explanation. Delivery: 2 days after I review the issue and receive the necessary access. One correction round for the agreed fix is included.
Please message me before ordering so I can confirm the scope. A redesign, new backend, payment integration, malware cleanup or recovery of lost data needs a separate estimate. Production changes are applied only after your approval. Use temporary access; do not put passwords in public messages.
The attached original demo shows client and server validation, an error that keeps the user's text, and a successful retry. It is a local portfolio demonstration, not a customer project.
