how to hide “category” followed by name of category at top of page

Note: I’m looking at it in the live preview and when I try to enter snippets of code that hid this on my current theme, the code isn’t working. This is the code I currently have, some of which hid this issue on my current theme, but not when I try to plug it in on the Koji theme:
#site-logo {
display: none;
}
.home #site-logo {
display: block;
}.archive .page-title {
display: none;
}.post-meta .post-category {
display: none;
}.site-header a {
font-weight: bold;
}#comments, #respond {
display: none !important;
}.nav-subtitle, .post-navigation .nav-links {
display: none;
}

Figured it out! For “blog” category, for example, I put the following in the Additional CSS area:

.category-blog .archive-header {display: none !important;
}

Tried your code above but it didn’t work, I tried adding .subheading instead and it work on my side. Glad to found this little tweaks for a great theme. Here’s the updated code:

.archive-header .subheading {display: none !important;}
