How to make to Show link after click on button

Hi,

I hope someone help me to make this,

I need to Use a Button and i need pop up window come and show links or Expand little box under to button and show links when click the button.

and How i make Post Title bold? i can set it to make bold on my Style.css but the problem is title and categories under H2 and when i edit style sheet title and categories become bold. i need only Title to become bold.

Can i add a text format as H7 and use it for Categories? if can please tell me the code and which file i have to edit. then i can use H2 bold for title.

Hope some kind person will help me to make this solve for me…

Thank you…
