MD021 - no-multiple-space-closed-atx¶

Description¶

This rule is triggered when more than one space is used to separate the heading text from the hash characters in a closed ATX style heading. The violation can occur on either side of the heading text.

Rationale¶

Extra space has no purpose and does not affect the rendering of content. Using a single space keeps the source clean and consistent.

Examples¶

Invalid¶

#  Heading 1  #

##  Heading 2  ##

###  Heading 3  ###

Closed ATX headings with multiple spaces inside hashes.

Valid¶

# Heading 1 #

## Heading 2 ##

### Heading 3 ###

Closed ATX headings with single space inside hashes.
