Thanks both of you.
Can you tell me what would be causing the lettering overlap on my home page
http://ordinaryjoe.ca/endthemadness/
The titles of my individual pages are showing up in the Nav Bar and then underneath it causing some overlap. Do I need to increase the size (capacity) of the Nav Bar or increase the space for the header?? Can you tell me what to do. Remember, I am a novice.
Thanks,
Don
