In the forum I just got another problem where a member was asking about how to delete the blank space between the blog title and the navigation menus. He was using Structure Theme by Organic Themes. Here I tried to solve the problem by using CSS (Cascade Style Sheet). Just Copy the below code and replace only that portion in your WordPress CSS. By the way, If you are using free WordPress.com blog then you have to purchase their Custom CSS upgrade.
If you have any question related to css, feel free to ask using the comment box below.
** Just Change the Height portion according to your necessity.
