Your skin file probably has a fixed or maximum width. You'll need to make a change to your skin file.

I looked at your site and see that the skin is or is based on the DNN-Blue skin. That skin actually comes with several variations. There is one with a full screen width, and one with a fixed width. If you look at those files, and compare with your existing skin file, you'll see where to change the width specifications.

In my website(http://www.afticom.com) home page , first two paragraph showing a nice look...but in 3rd and fourth one showing a different look..all text in that home page i selected same style...like font ,colour,size...everything same...but y this last two paragraph is showing different look...

Look at the contents of the module (I assume it is a text/html module) in "Source" mode. I'm guessing that there are tags in there that you don't know about.
