Add taxonomy description to Header Post Category Archive and Post Tag Archive

Hi,

I'm trying to change the look of category and tag archive pages.

I 1st. hided Page Title from Post Category Archive and Post Tags Archive pages and 2nd. added one template tag ({{post_title}}) and some text to those same pages. Now, I would like to add taxonomy-description for both category and tags Archive Pages. I can't find the needed template tag to use (I tried taxonomy-description but doesn't work...).

I know I can copy text to the header element but it would be nicer if I could keep managing content where it belongs (in tags and categories description). Is there a template tag that I can add to the header element? I searched for it but I wasn't able to find it.

Best

Joao

P.S: Before using elements, I tried using some CSS code I adapted after searching our forum (see below).

CSS code:
/* Remove page title from Categories */
.category .page-title {
display: none !important;
}

/* Remove page title from Tags */
.tag .page-title {
display: none !important;
}

This solution didn't work because besides hiding page titles from those pages it also hided the taxonomy description I'm looking to maintain (now moving it to the header element).
