i was going to mention 3dschools, but someone beat me to it.
The problem I have wysiwyg or canned apps, or even raw .txt files is that your stuff always gets hijacked somehow.
If i download a html page using filezilla, to folder or my desktop, open it in text file.. when i save it by abiword, thinking i had just edited a .txt file, abiword puts its own 'stuff' in there!.
open office, windoze, even when you want to work with your html file in a text editor, it seems all these apps jump in to 'help' you make a web page.
i end up renaming my name of a html page on the website to a .txt before downloading it then put it back on the webserver as text, and renaming it there.
