Proovi leht (test)

Tsau! 

Lisan koodi alljärgnevalt. Katseta ja proovi kas saad õigesti tööle. Kirjutan siia probleemid inglise keeles, siis lihtsam aru saada – 

1. Elements “Põrand” and “Mahuti” can not be placed on same square – needs to trigger error alert(text + red square) 
2. Error alert red square only appears if the grid square is visible, when there is already põrand or mahuti then the red color appears under these elements so not helping. Red color needs to appear on top of all elements dragged to the square. 
3. Also when a wall and post meet on square corner then its an error – alert trigger.
