Sb_betteramp.ee_addon is a project mainly written in PHP, it's free.
Use the best ampersand available. Wraps ampersands in ABBR tags for styling with CSS attribute selectors.
One of the guidelines from the seminal book by Robert Bringhurt - "The Elements of Typographic Style" states that "In heads and titles, use the best ampersand available". This plugin attempts to allow you to do just that with your text on the web.
To use this plugin, wrap anything you want to be processed by it between the following tag pairs. Entry titles and headline text works best.
{exp:sb_better:amp}{title}{/exp:sb_better:amp}
1.0.1 - Reworked the plugin and improved parsing code. Hey, it actually works now! 1.0 - Initial release
