Grav is a great tool to document my work. Congratulations to the developers.
I chose the Learn theme that is most appropriate for my need, but I need to integrate it visually with the rest of the site.
I tried using IFRAME, but let’s face it it’s not pretty.
Site with IFRAME: https://www.mundophpbb.com.br/docs/phpbb.html
So I decided to redesign the LEARN theme, it was easy, I created two files, header.html.twig and footer.html.twig and included in the base.html.twig file
according to the link below, however I can’t undo the sidebar and place it next to the content,
