I will fix HTML CSS and javascript bugs or make your site mobile friendly
Arthur
About this gig
Is something broken on your website, or does it look wrong on phones? I fix front-end problems in HTML, CSS and JavaScript on existing sites: layouts that break, menus that don't open, overlapping text, buttons that do nothing, pages that don't fit small screens.
WHAT I CAN HELP WITH
- Mobile responsiveness (phone, tablet, desktop widths)
- CSS layout bugs: alignment, spacing, overflow, fonts, images
- Small JavaScript bugs: menus, sliders, form checks, click handlers
- Short note listing what I changed and why
HOW IT WORKS
Upload your site files or a zip of the repo (no passwords), list the pages and the problems, and say which devices look wrong. I reproduce the issue, fix it, test at several screen sizes, and send back the changed files.
GOOD TO KNOW
- Static and front-end only. No WordPress or CMS admin access, no backend, no databases, and I never need your passwords.
- Please send files you have the right to share.
- I use AI-assisted tools to find and fix issues faster, and I test and review every change myself. Tell me before ordering if you'd prefer no AI tools.

I build small, practical things: clean one-page websites, spreadsheets that stop being a headache, messy data cleaned up, and Python scripts that do a boring task for you. I use AI-assisted tools to work faster, and I personally test and review everything before it reaches you. Tell me if you'd rather I not use AI tools and I'll respect that. I keep scope clear, ask questions up front, and show you work early so there are no surprises. I'm Arthur, a final-semester developer in Rio de Janeiro, Brazil (BRT), online about 10 h a day for fast replies. Portuguese is my native language.

FAQ
Can you fix my WordPress site?
Not through the WordPress admin. I only work on front-end files (HTML, CSS, JS) that you upload. If you can send the theme's CSS or JS files, message me first and I'll say if it fits.
Do you need my website password?
No, never. Send the files or a zip of the repo. I deliver the changed files and you upload them yourself.
Can you add new features or redesign the site?
Not in this gig. It covers fixing bugs and responsiveness on an existing site. For anything bigger, message me first and I will tell you honestly whether I can help.
Will you test on real phones?
I test in browser device modes at phone, tablet and desktop widths. I can't promise every single device, but I'll cover the common sizes.
Do you use AI?
Yes, AI-assisted tools help me find and fix issues faster. I personally test and review every change. If you want no AI tools, tell me before ordering.
