title: jquery find element by specific class when element has multiple classes
body: <p>So I am working on something that wasn't well thought out in the build from the backend team. That leaves me with a document full of divs. </p>
  
  <p>What I am doing is rolling back from the element I need to click on, get the parent container then find an element within the parent which has <code>class="alert-box warn"</code>, <code>class="alert-box dead"</code>, etc... Essentially, I'm trying to use multiple class selectors on each element. When I try to find just <code>alert-box</code> it doesn't seem to be working right. I'm assuming because it has <code>warn,</code>dead, ``fine, etc... </p>
  
  <p>How can I find just <code>alert-box*</code> or equivalent to a wildcard concept?</p>
