Test the code example provided to you: When moving the mouse over a list food elements each element must change the backgroundcolour to grey.
Make sure that you have the title <h1> and have the correctl filename: lu06.s07.html
After moving the mouse over the colour area the background-colour should change randomly. Behind this effect there is a sophisticated Math-Operation.
Replace the math-method with a simple increment operation with step-size 1.
Start with the colour value of 0.
Add another area for the a right-click event.
Start with a colour value of 120
Decrement step-size is 2
Add another area for the a left-click event.
Start with a colour value of 240
Increment step-size is 5
Add another area for the a left-click event.
Start with a colour value of 240
Increment step-size is 5
Add another area for the a mouseover event.
Start with a colour value of 360
Decrement step-size is 10
Add to all four textareas a mouse-middle event which resets all colour to the initial values.
Hint: To get the initial values, you need to store te values in separately in the first place: either in 4 variables or in a array with all four initial values.
