Blank Lines

Markdown automatically joins elements such as text, list items, and code blocks, if there are no different types of elements between them. For example, if you create two lists (using the Markdown asterisk notation) with a blank line between them, the Markdown parser will automatically join them into a single list. You can use the following methods to add blank lines in your Markdown code:

    To add a single extra line after a paragraph, add two extra spaces at the end of the text.
