How to change width in bootstrap?

Question

Layout

Hello, I'm learning bootstrap, and I came across an incomprehensibility.
Here, according to the standard, there is a size of 1170px 12 columns of 30 px
This is all fine, but if I have a design for example 1200px\960px\1000px?
How do I prepare a bootstrap for my specific project? How do I prepare it for 960px?

Answer 1

1. Get into the sources and change the variables there.
2. Build a customized version at getbootstrap.com/customize
The second option is faster, but the first one gives potentially more benefits and knowledge (if you choose it - download better sass sources instead of less, the fourth bootstrap will already be made on sass)

Answer 2

I use bootstrap 4 files for high resolutions, 1600px (HD+), 1920px (Full HD), 2560px (Retina 1440p), 2880px (15" Retina), 3840px (UHD), 4096px (4K), 8192px (8K).
Files freely available Bootstrap 4 Grid for large screen resolutions
