Investigate centralised navigation elements

[sha0001]

Can the navigation bar be pulled from an external source, rather than embedded directly in the html of the page? This will allow for easy duplication, as well as managing changes, rather than having to update each HTML page individually.

iframes seem to be an option.

However may need to investigate what impact this might have on SEO (google searching).

Interestingly the W3Schools site seems to write it on each page... what a nightmare! I guess you could potentially create some way of automating the changes, but for only a handful of pages it might be easiest to just update manually and copy/paste.
