I am working on setting up a prototype within Codepen, using Bootstrap 4.

I am trying to figure out how to change the default breakpoints. I have the BS4.6 link as https://maxcdn.bootstrapcdn.com/boot...tstrap.min.css

I've read over the documentation here, but it doesn't seem to be offering a solution to my particular issue: https://v4-alpha.getbootstrap.com/la...ve-breakpoints

I am not looking for media queries, but instead to change the default pixel ranges for lg, md and sm breakpoints.

Any suggestions?
