I wasn't expecting it to work on touch-only devices but the left "leg" worked. But the right "leg" didn't. Is it possible to let it work on touch devices by div

I wasn't expecting it to work on touch-only devices but the left "leg" worked. But the right "leg" didn't. Is it possible to let it work on touch devices by dividing the screen into two halves such that tap on left register for left and tap on right registers on right? Or is the intention here to keep it vintage and not make it work on touch devices?
