Four card section with Grid layout and dark theme switch CSS only

Hi there! In this challenge i really wanted to do the card placement using only grid layout and it was easier than i thought! I also added a dark theme, it works by only css. The switch is made with has(), if you want to understand how it works this is the source where i saw this.
