<div class="explanation">
<div class="inner">
<p>jQuery and its cousins are great, and by all means use them if it makes it easier to develop your application.</p>
<p>
If you're developing a library on the other hand, please take a moment to consider if you actually need jQuery as a dependency.
Maybe you can include a few lines of utility code, and forgo the requirement. If you're only targeting more modern browsers,
you might not need anything more than what the browser ships with.
</p>
<p>
At the very least, make sure you know what <a href="https://docs.google.com/document/d/1LPaPA30bLUB_publLIMF0RlhdnPx_ePXm7oW02iiT6o">jQuery is doing for you</a>, and what it's not. Some developers believe that jQuery
is protecting us from a great demon of browser incompatibility when, in truth, post-IE8, browsers are pretty easy to
deal with on their own.
