How to add custom header and footer to my help center page?

All the helpcenters has special DIVs with the ids as faqprime_desktop_custom_header and faqprime_desktop_custom_footer (on mobile device the corresponding IDs are faqprime_mobile_custom_header and faqprime_mobile_custom_footer) which can be modified using the GTM to add a custom header or footer on the helpcenter. 

Note: These IDs are present only in the logout state of the helpcenter.

 

Sample GTM Code 

<script>
  var headerhtml = '<My Custom Header>'

  var footerhtml = '<My Custom Footer>';
  
  if (document.getElementById("faqprime_desktop_custom_header"))
  {
    var c_header = document.getElementById("faqprime_desktop_custom_header");
    c_header.innerHTML = headerhtml;
  }
  
  if (document.getElementById("faqprime_mobile_custom_header"))
  {
    var c_header = document.getElementById("faqprime_mobile_custom_header");
    c_header.innerHTML = headerhtml;
  }
  
  if (document.getElementById("faqprime_desktop_custom_footer"))
  {
    var c_footer = document.getElementById("faqprime_desktop_custom_footer");
    c_footer.innerHTML = footerhtml;
  }
  if (document.getElementById("faqprime_mobile_custom_footer"))
  {
    var c_footer = document.getElementById("faqprime_mobile_custom_footer");
    c_footer.innerHTML = footerhtml;
  }
</script>
