Proposal

Switching px to em for media queries.

Motivation and context

When I want to switch units from px to em, I will also need convert 0.02 (for px) to 0.00125 (for em) in breakpoint-max function which is now hardcoded.

What do you think?

Just to be sure to understand the request, you'd like a new Sass variable set to .02 so you can override it on your side, instead of the following?

bootstrap/scss/mixins/_breakpoints.scss

Line 45 in 5708adc

@return if($max and $max > 0, $max - .02, null);

[illycz]

Yes, exactly.

I don’t mind making it customizable via a Sass variable. I’ve proposed a solution in #41195—let’s see what the other core team members think! 🙂

Do we still need this at all? Feel like #41046 was hinting at not needing it.

[illycz]

@mdo Yes, I know about that, but it's planned for v6.

Probably not. This could just be a temporary workaround for v5, and it could be removed entirely in v6. 🤷
