As you can see:

1. Header --> Brown
2. Left Column --> Green
3. Central Block --> Red
4. Right Column --> Blue
5. Foot --> Yellow

And I design layout that has the same appearance in:

1. Firefox 3.5
2. IE
3. Opera
4. Safari
5. Firefox 24.0
6. IE 10
7. Chrome 30.0

There is the second part of homework3.
