Please DO NOT change index.html though. Change style.css so the page works as described below:

• The page consists of a header, a footer, and 9 blocks between them.
• The width of the blocks must be 300px.
• The height of each of the blocks (including both header and footer) has to be 100px.
• When hovered, the block height must increase to 200px.
• Please use these colors:
  • header is blue
  • footer is black
  • important is red
  • interesting is green
  • surprising is orange
• There should be no vertical spacing between the blocks and the edges of the page.
• Place the blocks so that they are horizontally centered on the page.
