how can i design a CSS style for comment boxes for a Social Networking site. Need some sample code

i have created a Social networking site in PHP. but am not good in CSS. Comments for images, and texts(status) are not good looking, does not have a good separation from each others.

So can anyone give me a CSS style for my site(like facebook having), which follows below logic,

  <table class="myTable" width="400">
 <tr  class="image_posts"><td> <img src="img1.jpg">  </td></tr>
        <tr class="image_comments"><td>   COMMENT-1     </td></tr>
        <tr class="image_comments"><td>   COMMENT-2     </td></tr>
        <tr class="image_comments"><td>   COMMENT-3     </td></tr>

    <tr  class="text_posts"><td> STATUS-1    </td></tr>
        <tr class="image_comments"><td>   COMMENT-1   </td></tr>
        <tr class="image_comments"><td>   COMMENT-2   </td></tr>
        <tr class="image_comments"><td>   COMMENT-3   </td></tr>
 </table>

Conditions:

• long "comments or status"(for example, text with 100 letters) should not exceeds the table width. it should split into 2-3 rows.


• Comments and text(status) posts should be easily separately identifiable by the user.

Can anyone please give me the code. i have done with my graduation project. i know PHP, but dont know CSS. so please, help me..
