Markdown Line Break Syntax#

Add two or more spaces at the end of a line, then press the Enter key to create a line break (<br>).

Best Practices for Line Break Usage#

Almost every Markdown application supports adding two or more spaces for line breaks, known as trailing whitespace, but this is controversial because it is difficult to see spaces directly in the editor, and many people may intentionally or unintentionally add two spaces after each sentence. For this reason, you might want to use other methods for line breaks besides trailing whitespace. Fortunately, almost every Markdown application supports another way to create line breaks: the HTML <br> tag.

For compatibility, please add "trailing whitespace" or the HTML <br> tag at the end of the line to achieve line breaks.

There are two other methods that I do not recommend using. CommonMark and several other lightweight markup languages support adding a backslash (\) at the end of the line to create a line break, but not all Markdown applications support this method, so it is not recommended from a compatibility perspective. Additionally, at least two lightweight markup languages support creating line breaks without adding anything at the end of the line; simply pressing the Enter key (return) will suffice.
