Let say I usee app.js or a bootstrap cdm link for all my html pages but I dont want to add it to every single page. How can I make a index.html that includes it so all the other html pages first loads the index.html head and then its own head. I use javascript for my project.
I tried to search it upp but none of the questions were the same as mine. My school project used this method so I thought this was a good idea but I dont know how to fix it.
