I needed to understand how to have the ability when there's no publish i must have the ability to hide the DIV that controls the most recent blog publish only getting them appear when someone publish somethign on the blog..

Somewhat just like a position in joomla however in this situation i'm using wordpress

You should use the have_posts() function to identify whether you will find any posts informed, and do conditionals according to that.

    //... do HTML in here 

If there's not posts, the HTML, and most likely the div you're speaking about, will not appear. You may also make use of an else statement for any custom message if you will find no posts.
