Generating random Bootstrap patterns

For my research project, I need templates of webpages with Bootstrap and their screenshot, templates are in HTML format and are composed of different Bootstrap elements (navbar, cards, ...) in a random way.

I am looking for some Python library that will generate different possibilities of combinations of Bootstrap pages, so I can get the largest number of them

I expect to get a number of pages where each one contains a random set of Bootstrap elements in an organized way.
