Description
This PR adds visual feedback to the contact form submission. Previously, users did not receive any confirmation if their message was successfully sent or not, leading to confusion. A simple toast alert has now been added using basic JavaScript.

Heyy @pavitraag ,I was trying to resolve the conflict in style.css, but I’m facing some issues and not able to fix it properly. Can I send you the updated style.css file directly so you can help merge it correctly? I’ve made all the necessary changes in it. Let me know if that works, thank you!
