css style ：pre { white-space: pre-wrap; } cease to be effective！

[yxj1010]

I want the contents of the code block to remain unchanged and wrap automatically, how do I set it?

<pre> tags rendered by Marp Core's built-in themes are enabled auto-scaling instead of text wrapping.
https://github.com/marp-team/marp-core/tree/main/themes#auto-scaling-flags

You have to use a custom theme if you want to disable auto-scaling and apply white-space: pre-wrap to <pre>. Exclude code from the scaling targets by using @auto-scaling metadata.

/* @theme custom-theme */
/* @auto-scaling fittingHeader,math */

@import 'default';

pre {
  white-space: pre-wrap;
}
