* INSTRUCTIONS: Use col-[size]-[columns] to denote classes. Example: col-md-5 for version 2 or col-md-6 for version 1 will display a half-width column. Clearfix resets the float functions.
Columnize.css (version 1) uses in a 12-column grid layout system. Here's a tutorial., Version 2 is a 10-column system.
<div class="row">
<div class="col-md-12"><!--12 only applies to version 1. Version 2 maxes out at col-[size]-10.-->
<p>This will display cat full-page width. 12, 11, 10, 9, 8, etc. are abbreviations for 100, 90, 80, etc. percents. On phones, this will mostly display in one or two columns based on the sizing preferences and screens. See more in the @media queries in the CSS file.</p>
