HTML editor:

Use this handy WYSIWYG (what you see is what you get) editor to test your HTML.  If you are a person that learns visually this works great.  Create your page in normal view, then toggle <> to HTML view to see the code.  Make changes to the code then toggle back, it's a great way to learn.

How to use this editor:

You must have Internet Explorer version 5.5 or newer to use this editor.

I suggest that you always start with a table, set the number of cells, borders, and alignment.
Build your page, when you're satisfied with the results, press the <> button to view your HTML, highlight the HTML, press CTL + C, this will copy the code to your clip board.  Open Notepad, press CRT + V, this will paste the code to Notepad, save as HTML.   When you want to work on your page again, open your saved file,>Select All>Copy, then paste it into the editor in HTML view.
