Hi,

1. You should have additional css: 

.header-v9 .header-logo {

z-index: 99;

}

2. Would you mind describing more details about that ?

3. There is 1 way to do that:

Active child theme

Copy file footer 6 from footers/footer_6.php in current theme to child theme like exact directory.

After that, Edit some lines of codes, see the picture, then you can edit the width size.

Hi,

Thing you want to have in category page can't be done. You just only add the rest of  woocommerce products is in home page.

Thanks

Hi,

Yes, there is one way that is creating 2 widgets:  category widget and checkout widget, by adding these lines of code in child theme:

This is an example for register 1 widget:

<?php
add_action( 'widgets_init', 'ci_widgets_init' );
    if ( ! function_exists( 'ci_widgets_init' ) ) :    
        function ci_widgets_init() {        
            register_sidebar( array(            
                'name'          => __( 'Checkout Sidebar', 'ci_theme'),
                'id'            => 'blog-sidebar',            
                'description'   => __( 'The list of widgets assigned here will appear in your blog posts.', 'ci_theme'),            
                'before_widget' => '<aside id="%1$s" class="widget %2$s group">',            'after_widget'  => '</aside>',            
                'before_title'  => '<h3 class="widget-title"><span>',            
                'after_title'   => '</span></h3>',        
        ) 
    );    
}

You can use Shop sidebar for category widget instead of register a new widget for it.

Thanks

Kind regard.
