+This rule is triggered for code span elements that have spaces adjacent to the
+backticks:
+
+```markdown
+`some text `
+
+` some text`
+```
+
+To fix this, remove any spaces adjacent to the backticks:
+
+```markdown
+`some text`
+```
+
+Note: A single leading and trailing space is allowed by the specification and
+automatically trimmed (to allow for embedded backticks):
+
+```markdown
+`` `backticks` ``
+```
+
+Note: A single leading or trailing space is allowed if used to separate code span
+markers from an embedded backtick:
+
+```markdown
+`` ` embedded backtick``
+```
+
+Rationale: Violations of this rule can lead to improperly rendered content.
