Buon Giorno From Wetherby UK,
I’m looking for a tutorial that breaks down the essential know how with regards to building a horizontal nav with drop downs e.g. similar to this one featured here - http://www.sandersonweatherall.co.uk/ (This is too complex for me). Now I’m only after the basics but it need to be pure css please.
Guten Tag from rainy Germany,
There are a lot of tutorials out there for CSS dropdowns.
One which I found to be very helpfull in the past is the Suckerfish.
You can read more here: http://www.alistapart.com/articles/dropdowns, or here: http://www.htmldog.com/articles/suckerfish/dropdowns/
However, the menu you link to is more of a mega menu.
I found this tutorial to be great, too: http://net.tutsplus.com/tutorials/html-css-techniques/how-to-build-a-kick-butt-css3-mega-drop-down-menu/
Hope that helps
