Unbreaking Lines

HTML and CSS rely on “unbreaking” source code lines to create paragraphs. The original rules for this were very simple: line breaks in the source turn into spaces in the rendering. But this rule does not work for writing systems that don't use spaces, such as Chinese.

Formats that need to “unbreak” lines include:

• HTML
• XML/SGML
• TeX/LaTeX
• https://asciidoc.org/
• Markdown
