drupal how do i stylish the $content variable for a view ?

Hello

I face an important issue while trying to style the views i made on my website.
I have created a view block named $reg_articole_recente and i need to style it without changing the current node.tpl.php file.
I only need to change the specific block for that view.

How should i name the node-?-tpl.php?

Does anyone understand my issue?

here is my website: www.vernisaj.ro and the views are on the left side as 2x3 rows. I also have a view block on the right side.

Thanks

Gingic
