Hi @rebelsnotes,

To add “/” between the categories then please go to Appearance > Customize > Additional CSS and paste the below custom css code.

.entry-meta.category-meta .cat-links a {
    margin-right: 4px;
}
.entry-meta.category-meta .cat-links a:before {
    content: "/ ";
}
.entry-meta.category-meta .cat-links a:hover:before {
    text-decoration: none;
}
.entry-meta.category-meta .cat-links a:first-child:before,
.post-block .entry-meta.category-meta .cat-links a:before,
.post-img-wrap .entry-meta.category-meta .cat-links a:before {
    display: none;
}

Thank you!
