STEP 2: If you want to change the colours of the hearts, change the colours at the start of the script you just copied to the settings you require (these can be in the form 'magenta' or 'rgb(255,0,255)' or '#f0f').
THAT'S IT When your page loads hearts will float up from wherever your cursor wanders. Also, if you hold your mouse button down, lots of hearts will be produced. And like true love, the path of hearts does not always run the course and sadly some hearts will be broken before they reach their target!
