Hi, Kean!
1). Would you like to remove the footer completely or just footer widgets? In order to hide footer for the Home page completely add the following code under Appearance ->Customize ->Additional CSS:
.home .footer-widgets, #colophon {
display: none;
}
To remove widgets only, use the following code:
.home .footer-widgets {
display: none;
}
2). You may simply add it as a menu item to the Primary menu. Feel free to add specific class to the menu item in order to apply desired styles to it.
Regards,
Andre
