Bogleheads® Wiki 2016 annual report

From Household budgeting, the first citation below is displayed as 2 columns. I'm using a widescreen display.

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

 Sample Income and Expenses Worksheet,           from the FDIC Money Smart Information Booth

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.

The 2nd column starts at the 2nd link:

Working experience to date
From the documentation: Using will create columns with a minimum width of 30 em, allowing the browser to automatically choose the number of columns based on the width of the web browser. Choose a column width that is appropriate for the average width of the references on the page. A width measurement must conform to the format given in CSS 2.1 Syntax and basic data types: Lengths; in particular, there must not be a space between the number and the unit.

Using will force creation of a two-column reference list, and  will force creation of a three-column list, and so on. This feature is now deprecated in favor of the option described above, which is better suited to flexible formatting for a variety of display screen sizes, ranging from mobile phones and tablets to wide-screen "cinema" displays. Forcing a fixed number of columns has been disabled in mobile view.

The seems to work with great precision for any page with three or more references:
 * Heavy referencing: Retirement calculators and spending
 * Moderate referencing:Developed market bonds
 * Average referencing: Managing a windfall
 * Three references: GNMA

The effectiveness of using 30em for pages with less than three references is dependent on the size of the reference.

Perhaps two possible solutions:
 * 1) Set the em size dimension to a higher value for pages with less than three references.
 * 2) Use   for pages with less than three references.

With over 500 pages with references I have been using the most effective overall, which is extremely effective in highlighting  a huge percentage of page errors, namely mixed reference and note listings, misplaced and misnamed headers, not to mention many pages in need of updating.
