To answer your first question the, News is coming from a Snippet called
Ditto which is part of the current
core Snippets. Also in the sidebar is other snippets: ListIndexer and the WebLogin. These are not template variables but php scripts that are called using special markup from within the template. To see what I refer to go to: Resources->Manage Resources->Templates->MODx Host and click on it to edit it and look at it in the edit pane.
To address your second question: while I think it is important for you to learn CSS based layouts (Did you know that
CSS is now 10 years old?) it is possible for you to achieve the same result with tables. Just build your HTML page in the editor of you choice and create a new template. If it is just content you want to stick into the place where the news is you would use a Chunk for HTML and a Snippet for PHP generated code.
You should take one step at a time and learn how to create templates in MODx and then get yourself a great text editor like
UltraEdit,
Notepad++,
e-TextEditor,
HTML-Kit, or stay out of design view in Dreameaver and stay in code view. I guarantee once you try to fix a 5 deep table nesting in a text editor more than once you will be looking for a better way. Save your tables for the wonderful world of email template design. I am a realist though and I would rather you not get discouraged by the learning curve and be encouraged by how much fun you’ll have learning. [url
