LU06.S06 - Events - Color changing

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