How I Built a 3D Animated Greeting Card Platform Using Swiper.js, HTML5, and JS

Hey dev community! 👋

For the past few months, I have been fully focused on a passion project born out of a simple vision: to bring genuine human warmth back to digital messages. Today, most online greeting cards are just flat, static images or cold, fully automated AI graphics.

To solve this, I spent six months independently engineering Thank Cards, an intuitive, web-based platform that elevates traditional digital messages into immersive multimedia keepsakes.

In this post, I want to share the core technical breakdown, why I chose my specific lightweight front-end stack, and the hurdles I faced while building it.
