Placed all “expandable” code files and images in one subdirectory expandable of the top level directory.

This design makes it much more efficient to download, install, and use the “expandable” code.

Updated the Story Utility to handle issues in the text file format of a story file. This will make the utility more robust.

Also, last week error checking was added to the Story Utility but this was not blogged.

Posted stories on HTML 5 and CSS 3. These all point to external resources.

I discovered an annoyance in the expandable Javascript code. The problem was this. If you collapsed a section using the button at the bottom of the section, you might then find yourself further down in the file. The reason for this odd behavior is that the scroll position of the document tries to remain at the scroll position of the button but now that the section and button have disappeared that scroll position now references a place further down in the file.

The fix was this. Compare the scroll position of the document with the scroll position of the icon at the top of the section that controls expand/collapse. If the document scroll position is too large a value (too far down) then decrease that value to make the icon visible.

The expandable files and zip are updated.

I added a section on the CS 4000 site called Student Sites Fall 2010.

This section has a link from each student’s name to their site if it exists.

3 students have sites that start to go beyond the “Hello World” level.

5 students have “Hello World” sites.

4 students have not even sent me a link to a simple “Hello World” site. This bothers me!

I made a number of improvements to the Story Utility, enhanced Synchronized Google Maps and made its story much more informative, and converted my older web development information page into a suite of distinct stories.

This information is now posted at my northeastern.edu site.
