title: fadeIn/fadeOut specified div on click of another div?
body: <p>I am creating something and I was wondering, if anyone can help me with one problem there.
  I have no ideas, how can I make a javascript that will always hide specified div id, and reveal it on a click of another div (for example an button).
  EDITED: </p>
  
  <p>So let's say I have 4 buttons.</p>
  
  <pre><code>&lt;div class="section" id="info" style="margin-top: 0px; "&gt;
  &lt;h3&gt;&lt;a href="#"&gt;Button&lt;/a&gt;&lt;/h3&gt;
  &lt;/div&gt;
  
  &lt;div class="section" id="search" style="margin-top: 0px; "&gt;
  &lt;h3&gt;&lt;a href="#"&gt;Button2&lt;/a&gt;&lt;/h3&gt;
  &lt;/div&gt;
  
  &lt;div class="section" id="player" style="margin-top: 0px; "&gt;
  &lt;h3&gt;&lt;a href="#"&gt;Button3&lt;/a&gt;&lt;/h3&gt;
  &lt;/div&gt;
  
  &lt;div class="section" id="socials" style="margin-top: 0px; "&gt;
  &lt;h3&gt;&lt;a href="#"&gt;Button4&lt;/a&gt;&lt;/h3&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Now let's say I have an content in another div, that I want to fade in on the click of the first button from above.</p>
  
  <pre><code>    &lt;div id="content-reveal"&gt;
      &lt;p&gt;something here&lt;/p&gt;
      &lt;/div&gt;
  
      &lt;div id="content-reveal-2"&gt;
      &lt;p&gt;something here&lt;/p&gt;
      &lt;/div&gt;
  
      &lt;div id="content-reveal-3"&gt;
      &lt;p&gt;something here&lt;/p&gt;
      &lt;/div&gt;
  
      &lt;div id="content-reveal-4"&gt;
      &lt;p&gt;something here&lt;/p&gt;
      &lt;/div&gt;
  </code></pre>
  
  <p>Okay... So positions has been set and everything is on correct place.</p>
  
  <p>So... How can I hide the <code>&lt;div id="content-reveal"&gt;</code> and show it when someone click on my button?</p>
  
  <p><strong>I have 4 different buttons with 4 different content. So on click of same button, content disappears again, and on click of another button, old content disappears, new one appears.</strong></p>
  
  <p>Simple question, hard task for me... </p>
  
  <p>If anyone can help, I really appreciate...</p>
