Invisible category

Hi,
I created my slider category, but I don’t want to anyone see it, can I make it invisible?
The category name is featured and my site is http://herekore.pl
Also Is there any chance to hide all categories, but only on slider?

Hi @elisavet,

Try this css code:

.flex-caption .post-categories {
display:none;
}

Thanks,

Cristian
