Remove sidebar for both desktop and mobile users

[ched]

Hello,

I have added a hook to remove side bars ( Categories & Action & and Choose Currency) from all product pages.

But this works only for Desktop and not for Mobile. What I should add to be removed from all type of devices?

Here is the hook that I've added :

 

<?php

# Cart Sidebar Removal / Resizing v8.1 Hook
# Written by brian!

function cart_remove_sidebars_hook($vars)
{
//      $validtemplates = array("domainregister","domaintransfer");
        if ($vars['inShoppingCart'] && !in_array($vars['templatefile'],$validtemplates)) {
                $head_return = "<style>#order-standard_cart .cart-body { width:100% !important; }
                .cart-sidebar {display: none;}</style>";
                return $head_return;
        }
}
add_hook("ClientAreaHeaderOutput",1,"cart_remove_sidebars_hook");

 

Thank youu
