Designing the UI using Bootstrap-Flask

There are several ways to render context data with look-and-feel to the Jinja2 templates without stressing too much about downloading the resources files or referencing the static files from the content delivery network (CDN) repository and importing them into the template pages to manage the best UI design for the renditions. One of the most ideal and up-to-date options is Bootstrap-Flask, a far different module from the Flask-Bootstrap extension module. The latter uses only Bootstrap version 3.0, while Bootstrap-Flask can support up to Bootstrap 5.0.

pip install bootstrap-flask
