MD019 - no-multiple-space-atx

Description

This rule is triggered when more than one space is used to separate the heading text from the hash characters in an ATX style heading.

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

Headings with multiple spaces after hash.

Valid

# Heading 1

## Heading 2

### Heading 3

Headings with single space after hash.
