Need help to move Add to cart button above the description tab on product page in opencart v2.3 on smaller screens
<p>In opencart v2.3, Product page hierarchy on smaller screens is as follows:</p>

<ol>
<li>Header</li>
<li>Product Image</li>
<li>Description and Review tab</li>
<li>Price, options, Add to cart button</li>
<li>Footer</li>
</ol>

<p>This happens only on smaller screens, Add to cart button on product page in opencart is below the description tab. If I have a long description then it will effect sales.</p>

<p>I want to move the add to cart button above the the description tab and below the additional images.</p>

<p>This is my Website <a href="http://www.festivetaste.com" rel="nofollow noreferrer">www.festivetaste.com</a> and
everything works well on larger screens.</p>
