# `MD018` - No space after hash on atx style heading Tags: `atx`, `headers`, `headings`, `spaces` Aliases: `no-missing-space-atx` Fixable: Some violations can be fixed by tooling This rule is triggered when spaces are missing after the hash characters in an atx style heading: ```markdown #Heading 1 ##Heading 2 ``` To fix this, separate the heading text from the hash character by a single space: ```markdown # Heading 1 ## Heading 2 ``` Rationale: Violations of this rule can lead to improperly rendered content.
