I need my middle blocks to be looked same as the left and right blocks. same color same fonts. Just like this site (nukemods). what are the changes that I need to..

By look the same do you mean cell images, spacing, padding, font, width, etc.?

Please post a link to your site in your reply as well.

I'm using the theme Aphrodite_Blue , when ever I add a new block to the middle it doesn't look same as the right or left. with highlighted title heading. In this page (nukemode) even the middle blocks look same as the right and left blocks. while title blue background. How do I get mine look like that..

sorry I don't have my site up yet..to put a link

No they dont, centre blocks have no headers, the news items below do.
