I hope you are using Firefox for your visit to this site today. Opera may mess up some formatting, but not as badly as a few versions of IE. Firefox is free!
I do not use an HTML editor. Instead, I manually type in code with gEdit on an IBM Thinkpad T-40 running Debian 5.0 (lenny). Each page is checked with the W3C validation service to make sure that the XHTML (strict) code is valid and that there are no problems with the Cascading Style Sheets (CSS). Images have been edited with GIMP. JavaScripts were provided free by The JavaScript Source and The JavaScript Kit.
You are welcome to contact me by email if you have comments about the page design or JavaScripts.
