hide category title


I would like to hide the title of the category. i tried this :

article.post .post-categories a, .post-inner-content .cat-item a {
display: none;

but only the title of the post is gone. i would like to hide the title when we are in the category.
my website to understand : http://levoyageurmalin.fr/category/avions/


Hey there,
I hope you’re doing well today

Because of how this was coded its not possible to hide it with CSS.
What you can do is submit a feature request Git Hub under issues, to have blog title category title separate from the title, so it can be manipulated instead of joined together.

Submit Request here: https://github.com/puikinsh/Activello/issues

Sorry for the inconvenience

Best Regards,
