<p>This plugin adds the Modernizr to your WordPress installation.<br />
Modernizr is a small JavaScript library that detects the availability of native implementations for next-generation web technologies, i.e. features that stem from the HTML5 and CSS3 specifications. Many of these features are already implemented in at least one major browser (most of them in two or more), and what Modernizr does is, very simply, tell you whether the current browser has this feature natively implemented or not.</p>

Modernizr for WordPress

The 2.8.4 version inserts broken javascript link.  I posted a message about this in the support section for the plugin and the author has not responded or fixed the problem.  Now, any site that I've added this plugin to can be broken if the user runs an update.  

Instead, if you need Modernizr, insert the following into your header.php file just after <?php wp_head(); ?>:

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/modernizr/2.8.3/modernizr.min.js"></script>

<p>iE CSS and SCRIPT Definer allows you to define CSS or SCRIPT code targeted to specific versions of internet explorer. This allows on the fly editing and fine tuning of design anomalies that are common with iE. Using commented conditionals that ie reads and understands, one can now target a range of or specific versions if iE to apply the custom fixes. This saves a great deal of time as extra separate css or js files are cumbersome when small fixes are needed.</p>
