title: Show or hide a element by class when you click a specific link
body: <p>I'm using WPBakery Page Builder for tabs. And I want to show a text block outside the tab section (on a diferent row) with a specific class when first tab with href #1521496635357-e8313acf-e8c2 is open and another text block when the secound tab with href #1521496635380-99d0c08b-67d8 is open (and the first text block to be hidden).</p>
  
  <p>Can you give me a hint with CSS or JS? </p>
  
  <p>Thank you!</p>
  
  <pre><code>    &lt;ul class="vc_tta-tabs-list"&gt;
      &lt;li class="vc_tta-tab vc_active" data-vc-tab=""&gt;
      &lt;a href="#1521496635357-e8313acf-e8c2" data-vc-tabs="" data-vc-container=".vc_tta"&gt;
  &lt;span class="vc_tta-title-text"&gt;PRIX STANDARD&lt;/span&gt;
  &lt;/a&gt;
      &lt;/li&gt;
      &lt;li class="vc_tta-tab" data-vc-tab=""&gt;
  &lt;a href="#1521496635380-99d0c08b-67d8" data-vc-tabs="" data-vc-container=".vc_tta"&gt;
  &lt;span class="vc_tta-title-text"&gt;PRIX BUDGET&lt;/span&gt;
  &lt;/a&gt;
      &lt;/li&gt;
      &lt;/ul&gt;
