You add this code to your functions.php file. If you're going to be adding custom code like this, I recommend you use either the PageLines Framework Base Child theme or the PageLines Customisation plug-in both available from the Store. Adding custom code to PageLines Framework functions.php will most likely break your website. However, adding your code to the base child theme or the customisation plug-in will not break you website.
Base Child Theme (For Developers to create new child themes).
Download and Activate Instructions: To get the Base child theme, login to your Wordpress Admin Dashboard --> PageLines --> Store --> Themes --> Add Themes --> Top Free --> Base Theme --> Install
Pagelines Customize Plug-in (This contains style.css and functions.php, just like a child theme.)
Download and Activate Instructions: To get the Pagelines Customize Plugin, login to your Wordpress Admin Dashboard --> PageLines --> Store --> Plug-ins --> Add Plug-ins --> Top Free --> Pagelines Customize Plugin --> Install--> Activate.
Once activated you can find the style.css and functions.php files in: wp
