💌 How the Formspree Contact Form Works
Don’t want to mess with PHP or backend servers? No worries. I’ve used Formspree – a simple, free tool that lets you collect form submissions directly in your email.
Just sign up at Formspree.io, replace the form’s action attribute with your endpoint, and you’re good to go. Visitors can message you right from your website — securely and efficiently.
🌗 Day & Night Mode Toggle
Users can switch between Light and Dark themes with a single click. This feature not only adds a modern touch but also improves usability, especially for night-time visitors.
The theme switch is persistent using localStorage, so the next time a user visits, it remembers their preferred mode.
