The easiest thing to do is to get hold of a copy of Dreamweaver. Latest version will set you back a few hundred quid, but old versions abound on ebay, etc. I did our whole site on Dreamweaver 3.0, which is about 10 years old, and it didn’t cause any significant problems: French Alps Mountain Bike Holidays
Since doing the original version of our site, I’ve learned a lot more about modern web standards etc., but my ancient version of Dreamweaver still seems to be able to deal with pretty much all of them.
I’ve also started to learn bits of Javascript etc., to be able to do things like the changing photos on this page: Trails Info Page
Dreamweaver is a bit like MS Word for web pages. There’s a menu option or an icon for all sorts of things that would take forever to learn how to code.
If you get a decent html book and use it in conjunction with Dreamweaver, you’ll figure out pretty quickly what DW is doing and be able to tweak the code in places to suit exactly what you want to do.
