Few questions about fonts and menu tabs

Hi, First of all, you made really great job with Simple Catch Pro! but I'm green in CSS and other web stuff so I have few questions. My page : http://www.poradnikniemowlaka.pl (still testing it) 1. How can I change the font size for the H1 or H2 tags? This command doesn't change it, don't know why : h1 {font-size: 32px;} 2. How can I change the font style for the H2 tag and for the menu nav bar? 3. How can I change witdh for the menus in nav bar?  I want to move "Kontakt" menu to the right or to stretch all menus a bit to make it look good. 4. How to change the height of post image and text box on main page? 5. How I can turn off "comment's box" for "Kontakt" page or other ? 6. How I can change background in comment's ? 7. How I can change the font size and style in "Leave a comment"  and "1 comment, 2 comments, etc" above comments box for example here : http://www.poradnikniemowlaka.pl/?p=86 Thanks ! Darek
