Original link: https://yihui.org/en/2023/09/merge-blockquotes/ Older versions of Hugo use a library named Blackfriday to convert Markdown to HTML, which is not compliant with CommonMark (unlike Goldmark in newer versions of Hugo). One problem with Blackfriday is that blank lines inside blockquotes are treated as part of the blockquotes. For example, > One > Two will be

Original link: https://yihui.org/en/2023/05/fold-messages/ Most R Markdown users may know that code blocks can be folded in HTML output. Then @rkb965 asked a good question on how to fold messages and warnings.
