Bootstrap conflict with Hugo tale theme

I’m using tale theme GitHub - EmielH/tale-hugo: A port of the Tale theme for Hugo. Tale is a minimal theme curated for storytellers. . I’ve an about.html and contact.html which I had created some months ago with bootstrap which is having bootstrap tables and all which Is before coming to Hugo.

I can’t get rid of those pages. So after searching a bit and following someone, I’ve added the bs style in layout/partials/head.html and seems all other components in the theme got messed up.

Can i create my /contact and /about having its own bootstrap style or tables by inheriting the tale theme but additional bs tables and buttons.
