Hello!
This is an envelope I built for my friend.
She was so depleted from everything that happened at work, and at the crossroad between the old path and a new one. I wanted to encourage Her. Since I was learning CSS at the time, I thought I could make her something with it. Then, the idea of making an envelope flashed through my mind!
The techniques used here are not complicated. It's mainly made with different position tricks, but I spent hours tweaking the lines degree by degree, pixel by pixel lol.
When my friend received it, she was very surprised. I was glad that she liked it!
