Hi pdingle
In this case, you can set sticky for header only, sticky for top1 position is not ideal.
For the header:
1/ Open the file: /templates/gk_instyle/layouts/default.php
Look for this line:
<html class="<?php echo $option; if(isJoomla4()) echo ' j4'; ?> affix-top" lang="<?php echo $this->APITPL->language; ?>" <?php echo $tpl_page_suffix; ?>>
and add affix-top class as above
2/ Add this custom CSS:
.affix-top #gkHeader {
position: fixed;
width: 100%;
top: 46px;
z-index: 99999999;
}
.affix-top #gkContent {
margin-top: 222px;
}
