title: CSS selector based on textbox value
body: <p>I have an environment which supports CSS / bootstrap 3.2, - but NO javascript.
  I am trying to implement a list filtering solution using pure CSS selector + HTML.</p>
  
  <p>Suppose, I have 2 items in an HTML list element. I want to show only the ones matching the text entered in the input element.</p>
  
  <pre><code>&lt;form&gt;
    &lt;ul&gt;
      &lt;li class ="c1"&gt;c1&lt;/li&gt;
      &lt;li class="c2"&gt;c2&lt;/li&gt;
    &lt;/ul&gt;
  
    &lt;input type="text"&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>if I type <code>c1</code> in textbox, that should show only the first item.Is this even possible using pure css, no JS?</p>
