Hi @elpanda13,
Thanks for posting in.
The landmark for each stack is different, and in Ethos, there is no description. Still, you can change the archive title on the area in your screenshot.
The file responsible for that is
framework\legacy\cranium\headers\views\ethos\_landmark-header.php
You can copy the file to your child theme of the same path, like
\x-child\framework\legacy\cranium\headers\views\ethos\_landmark-header.php
Then edit it and include your description and text. Example,
<?php elseif ( is_category() || x_is_portfolio_category() || x_is_product_category() ) : ?>
<?php
$meta = x_get_taxonomy_meta();
$title = ( $meta['archive-title'] != '' ) ? $meta['archive-title'] : __( 'Category Archive', '__x__' );
?>
<header class="x-header-landmark x-container max width">
<h1 class="h-landmark"><span><?php echo $title; ?></span></h1>
<?php echo term_description() ?>
</header>
<?php elseif ( is_tag() || x_is_portfolio_tag() || x_is_product_tag() ) : ?>
<?php
$meta = x_get_taxonomy_meta();
$title = ( $meta['archive-title'] != '' ) ? $meta['archive-title'] : __( 'Tag Archive', '__x__' );
?>
<header class="x-header-landmark x-container max width">
<h1 class="h-landmark"><span><?php echo $title ?></span></h1>
<?php echo term_description() ?>
</header>
Thanks!
