A couple of weeks ago I was asking about a nav bar, I've read a book on css and I'm still struggling to comprehend whether or not I should use a div tag of ID tag I'm guessing an id. I want my logo (attached) as the top of the navigation, with an <ul> below it. Showing my link like home, gallery, contact us etc. I just don't understand if I should format everything as an ID in the external css stylesheet? or do I have the xhtml <ul> (un-ordered list) on every page, then that links to the external stylesheet. The thing is I want this on every page, and was hoping to create an id as the logo (attached), thought if I keep entering the <ul> will be cluttered and supposed to only have extreme individual page content (For SEO). I'm having problems understanding the concepts of nav bar. Thought I would've understood this by now after all the research I've done. Any help appreciated.
