If you write a tutorial for creating a template used in Joomla, you should have a working template yourself, no?!
Look at this: http://www.joomlatribune.com/Joomla-Tutorials/making-a-3-column-joomla-theme.html
Can you see, the text is cut off by the sidebar. This happens because the width of the content is not set correctly in the css.
And this guy is giving a tutorial on that?????????
