I’ll diagnose and fix one reproducible front-end issue on one existing web page, such as a broken mobile layout, overflowing section, non-working menu, or a small HTML/CSS/JavaScript interaction. You receive a code patch or updated files, a short explanation, and a desktop/mobile check. Fixed scope: one issue on one page in an existing site. You provide the source or repository access, the page URL if available, a clear description of the expected and actual behavior, and any screenshots or browser details needed to reproduce it. The 24-hour turnaround starts after I receive everything needed to reproduce the issue and confirm that it fits this scope. Excluded: backend, database, payment or authentication flows, new page designs, major rewrites, third-party outages, hosting, and ongoing maintenance. If the request is outside scope, I’ll clarify it before starting or quote a separate project. No promise of a business outcome or guaranteed traffic. FR : Correction d’un problème front-end reproductible sur une page Web existante. Vous fournissez le code, l’URL si disponible et les étapes de reproduction. Je livre un correctif et une courte explication dans les 24 heures après réception des accès et confirmation de la portée. Le serveur, les paiements, l’authentification et les nouvelles maquettes sont exclus.
