Mauricio and i discussed and he suggested me to work on a separate and a new branch gsoc-bootstrap .
I’ll do all my project work on this branch and will get it merge to the master at the end of project.
I continued implementing the bootstrap grid structure to further pages. That part was easy for pages like ‘variables’ but really tricky for some pages like ‘users’ as html is still not completely extracted from php files to twig. Also, there are pages for which parts of html are extracted to twig of templates and parts are still there in php files.
