Website Code Issue with Claude AI

I created a website code using Claude AI for my small business, but I'm facing an issue with the website. The code is ready with pictures and everything, but I need help resolving this technical problem. The ideal candidate will have experience in debugging and troubleshooting website code. The issue is exactly this: when I open the website from phone view, the items pictures size are not correct either too big or too small, second thing is that I need the website to send an email to notify customer when they make an order that their order is recieved. If you have the skills of doing this please send submit an application.
