<h4>Social Sharing By Danny</h4>
The simplest sharing links possible for Twitter, Facebook and LinkedIn.
Most WordPress plugins that add social sharing functionality are too ugly, heavy, complicated or poorly coded for my liking. This plugin aims to be better: simple, efficient and flexible.
<h4>No script dependencies</h4>
From itself, the buttons are actually plain text links which require no external scripts. It makes no sense to load over 50 kilobytes of scripts and styles for a functionality 95% of your users will not use.
<h4>Simple, yet pretty and user-friendly</h4>
You can have the plugin load two very small files to add icons and a pop-up functionality to the sharing links. This way, users do not have to leave your website after clicking a sharing option. Both files are optional and you are free to craft your own styles.
Features
<ul>
<li>Sharing links for Twitter, Facebook and LinkedIn</li>
<li>Simple icon styles with a hover effect</li>
<li>Simple script of just 426 bytes (with no additional dependencies) which will make the various sharing links open in a pop-up window.</li>
<li>A shortcode and a template function to display the buttons anywhere you want.</li>
<li>An overridable filter to customize when and where to display the sharing links.</li>
<li>Translation ready</li>
</ul>
