Any reason for using 600px here? Given that all doc example should wrapped around 80 chars a line, I think we can use a more fine grained value.

Suggested change
@media only screen and (max-width: 600px) {
/* 80 chars + the width of the toggle input + 20px of margin */
@media only screen and (max-width: calc(80ch + 142px + 20px)) {

  1. calc is not supported in media query:

Properties sometimes accept complex values, e.g., calculations that involve several other values. Media features only accept single values: one keyword, one number, etc.

  1. the 80 char lines is a limit in documentation text, not inside pre tags that take 100% width

  1. calc is not supported in media query:

That doesn't seem to be correct, according to https://drafts.csswg.org/mediaqueries/#width any <length> is a valid value, and IIUC that should include calc().

2. the 80 char lines is a limit in documentation text, not inside pre tags that take 100% width

I still think it would be a better value than 600px, that feels quite arbitrary to me.

Interesting, it does work on Chrome 105 but not on Chrome 102 (I've tested on Firefox 101 and Safari 15.5, both support calc() media queries). Given Chrome release schedule, should we ignore that incompatibility?

Some observations:

Is it possible/reasonable to add a linter rule in docs for cjs/mjs blocks, forcing <=50 or <=60 for first two lines and maybe <= 80 for the rest?

Another option is to keep this fix with hardcoded width and eventually somehow redesign the switch, e.g. by attaching it "outside" of code block.

I've opened #43506 to propose another suggestion: instead of applying the same breakpoint for all screen sizes, we could adapt to the length of the content. Let me know what you think.

So should we go with #43506 instead?

Both sound ok to me. I haven't tested your PR
