Div table with click event

[softwareguy74]

I need to create a ranking system that allows the user to click in a particular block at which time that block and all previous blocks will turn the color red.

I have attached a sample screenshot of what it would look like if the user clicked in block two. If the user clicked in block one, block two would clear, etc.

I really prefer to make this grid using DIV/CSS, rather than a Table.

Any help would be appreciated.
