In Win 7 Firefox, I see 2 columns in a single row. It appears as:

In Win 7 Chrome, I see a single column, but a newline occurs at the 2nd link.  Sample Income and Expenses Worksheet, from the FDIC Money Smart Information Booth

When I narrow my browser width, the column is eventually recalculated to display as a single column. MediaWiki:Common.css matches Wikipedia.

Should the pages be modified to utilize the 2nd form (no 30em parameter)? "Text replace" could be used to make the change.
