Hi,
1) Not by default, you would need to get a developer to make this modification for you: http://www.swiftideas.com/customization/
2) Sure please add this custom CSS to your theme options panel:
span.sku_wrapper {
display: none;
}
3) What did you want them to look like? You can adjust the colors, line thickness with CSS.
4) Sure, please activate your child theme, inside the child theme functions.php
file please add this CSS:
add_filter( 'woocommerce_product_tabs', 'woo_rename_tabs', 98 );
function woo_rename_tabs( $tabs ) {
$tabs['description']['title'] = __( 'More Information' ); // Rename the description tab
$tabs['reviews']['title'] = __( 'Ratings' ); // Rename the reviews tab
$tabs['additional_information']['title'] = __( 'Product Data' ); // Rename the additional information tab
return $tabs;
}
5) This based on the tags/categories from the item being displayed.
Thanks,
David.
