How to use bootstrap grid without bootstrap styles?

Question

css

Hello, the question certainly sounds stupid, but please understand me correctly. Let me just say that I am new to bootstrap. Recently I started to try to typeset on bootstrap and came across a problem, the problem is that bootstrap styles, in the layout that I'm typesetting, are not used at all. And of course, when imposition, it pretty bothers me. Can you please tell me how can I use only the grid, without styles for buttons, headings, etc. ? (This way I should end up with a responsive page, just with my styles)
Thanks in advance for your reply.

Choose only what you need.

Answer 2

The bootstrap grid includes .row classes, .col-* classes, and optionally .container. You can simply copy the styles of these classes into your styles.

Answer 3

you can download the bootstrap sources and include only the necessary, for example
, variables.less, grid.less, and when building, you will only have what you include.
