How does the Scratch editor implement block area folding? #22

Hello, esteemed author. I really like to use your micro:bit more extension. In the demo page you provided, I found an excellent feature: unlike MIT Scratch, the blocks section of your editor can be automatically collapsed and displayed fully again when the mouse is moved over the blocks. After using it for a while, I found that this collapse feature does not make dragging operation difficult, but very smooth and convenient. I would like to ask you how this feature is implemented?

This feature is implemented in Xcratch, on which MicroBitMore is based. Xcratch achieves the folding by modifying the css of the original LLK/scratch-gui.
