how to remove the head of category?

Please see the picture.

Hi @bryon,

I hope you are well today and thank you for your question.

Do you want to just remove “Category:” or whole header text?

Best Regards,

hi Movin,
remove the whole header text.

You can try achieving this by adding the following CSS code in the Custom CSS option of the latest version of Sparkling theme on the below path.

Admin Area -> Appearance -> Customize -> Additional CSS

.archive.category #main > .page-header {
    display: none;
