If you are just learning to use WYSIWYG Editors, you might be experiencing some of the following problems when using any free website creator software.
Like when you design with wysiwig editors like coffee cup and kompozer; it looks correct on the editor, but when you upload the saved file, its all jumbled up on the web.
The cause of this is that these are sites that have style sheets. You will need to open your css style sheet using Notepad and make the changes from there, provided that you understand how to use the style sheets. Then consider getting a basic book, The CSS Anthology and learn basic CSS and HTML.
Another reason things might look jumbled up, is that most free WYSIWYG HTML Editors tends to strip out codes/insert code that does not conform to w3c standards for HTML or XML, causing the outcome of the format to be different from what it should look it. So it might not be the CSS but rendering of tables that could be causing you problems. Thats the problem with free A way around this is to use a professional editor like Dreamweaver that complies to proper coding standards. And then even that can give you problems. And Dreamweaver is expensive.
For a cheap and fast solution, try opening your current site in a free editor like HTMLKit or better still, Notepad and try to edit your codes in from there. HTMLKit allows you to create a site using HTML/CSS code and preview it as you will see it on your computer at the same time.
Or if you still want to create sites using WYSIWYG editors I would highly recommend www.artisteer.com. It can be used to create themes for wordpress and HTML based sites. I have used it many times myself and it works very well. No formatting problems.
If you are serious about designing as a profession it’s best to learn Dreamweaver. There are several extensions that add features such as support for PHP Adobe Stock Exchange. Though this is best if you have the intention of becoming a website designer or webmaster.
