If you're talking about the process of making pages for the site by using a
site page editor (the so called WYSIWYG editors), then you might want to try
Amaya, Nvu/Kompozer., or even LibreOffice.
But I strongly advise you to be careful when using WYSIWYG editors, and to
test your pages regularly using an Internet browser, and also be prepared to
check the source code regularly too.
If you know how to define document types and encodings, it's useful to define
the document encodings to UTF-8.
W3C's HTML validation can be of good use too. Lynx, the minimalistic Internet
browser too.
Personally, I prefer to create pages using the good old plain text editors
like Gedit, which also supports syntax highlighting for many languages,
including HTML.

Have a nice day.
