WooCommerce: Remove sidebar for category pages on Twenty twelve child theme
<p>I would like to remove the sidebar on WooCommerce category pages and make the products there full width. I would very much appreciate any help with what code to put where. I have tried googling but haven't been able to get anything to work.</p>

<p>I am using a Twenty twelve child theme.<br>
