Originally created by @geektbee on GitHub (Oct 13, 2021).

I saw an issue where there were undesired scrollbars on code blocks (that's now fixed).

We're looking in the documentation, but can't find, for a way to enable scrollbars at a certain point. Like, maybe when the code goes over 20 lines, bam, institute a scrollbar.
Is this possible is the current state and we simply don't know how to find the documentation?
Or should this be a feature request, instead?

Thanks!

Hi @geektbee,

Adding something like this to your "Custom HTML Head Content" setting should get you most of the way there:

<style>
.CodeMirror-scroll {
    max-height: 300px;
}
</style>

Note: Adjust the 300px up or down to suit your need.

We don't support limited-heights on code blocks officially, so there may be potential side-affects or support breaks in the future, but the above may do what you need.
