title: Prestashop ThemeConfigurator module - 5th element wrongly displayed
body: <p>I'm totally new in prestashop/themeconfigurator but I want to help my wife to solve problem with wrongly displayed banners on website. She added 6 banners using themeconfigurator module and it should look like this</p>
  
  <pre><code>b1 | b2 | b3
  b4 | b5 | b6
  </code></pre>
  
  <p>but it looks like this</p>
  
  <pre><code>b1 | b2 | b3
  b4 | b5
  b6
  </code></pre>
  
  <p>I found that 5th banner has 66% width:</p>
  
  <pre><code>#htmlcontent_home ul li.htmlcontent-item-5 {
    width: 66.6667%; 
  }
  </code></pre>
  
  <p>For me this style is redondant and I don't know why it is in css file (hooks.css). As I found on github site (<a href="https://github.com/PrestaShop/themeconfigurator/blob/master/sass/hooks.scss" rel="nofollow">https://github.com/PrestaShop/themeconfigurator/blob/master/sass/hooks.scss</a>) this style is added by default.</p>
  
  <p>So the question is - is it possible to change this style using admin panel or do I need to change hooks.css source code? The problem is that I haven't got access to server so I can't edit source code.</p>
