you can do it like this

# наш контент в Nokogiri::HTML
nokogiri_html = Nokogiri::HTML(html_content)

# код нового элемента
new_element = '
<div style="color: red">
  Text
</div>
'

# добавление в начало body
nokogiri_html.at("body").children.first.add_previous_sibling(new_element)

# смотрим, что получилось
puts nokogiri_html
