Hello, I'm creating a web system and so far I've only created the header and a sidebar with the options. So far I was creating everything without bootstrap, but I want to put bootstrap elements like section and tables, since the creation of the header and sidebar gave me a lot of work due to little knowledge in web languages. I would like to know if there is any problem in continuing to create the other elements using the bootstrap so that I do not have to recreate the header and sidebar?
